The Flatpak is already packaged and works well. It just needs to be maintained from a person that joins the Inkscape community.
This would allow further improvements like Portal support and making the app official on Flathub.
Update: One might have been found!
Oficial repositories, unoficial repositories, flatpak, snap… What happened to just donwload the app from it’s own creator and install on your machine? Why do we need every app being touched by some rando before I can install it on my box?
Your wanted option is not gone, you can still download the binaries if the author presents them; or you can compile it from source. This is just another, more convenient way to distribute the program.
If you are looking to get your programs Windows-style, to download a binary or “install wizard”, then you can look into appimages.
Like any form of distribution however: someone has to offer this, be it the author or “some rando”.
Appimages have no install wizard. And Windows executables have some weird signature verification which Appimages dont have at all.
…
EDIT:
Appimagelauncher, gearlever, AM, etc. Which is the same as a install wizard since it integrates the appimage into the system. AppImages do not need to be extracted into the system which is what windows install wizards do.
Appimages came before these tools, and the tools (forgot the name GearLever, AppimagePool is another one) came afterwards.
They are structurally better as they are external.
That verification is interesting. So it is another appimage, used to verify appimages? Are all Appimages using that, if not what percentage of the ones you know? And are tools like Gearlever enforcing or using that signature check?
Usually if the appimage has a github release with a zsync you have that verification.
I don’t use gearlever, as far as I know gearlever doesn’t even let you sandbox the appimage like AM does. I don’t think any of those forces signature verification besides AppImageUpdateTool and that’s because that’s part of the zsync update process.
Interesting, will look into this. The issue is of course that these tools are optional.
But if they work, they may fix nearly many issues. Some will remain, for example many proprietary apps dont use Github releases, while these may be especially targets of fakes.
True. Still the most windows-like installation method.
If you mean downloading random stuff from random websites, yes.
But they dont have installers, so no verification, no moving to locations where executing is allowed (on Linux the entire home is executable which is a huge security issue) no desktop integration, no context menu, no file associations.

You still have to give the exec permission to the appimage.
Maybe no context menu depending on what you mean exactly, but the rest are fully possible and I do it on a regular basics with my appimages…
edit: Omg you are the guy from don’t use appimages, I see you haven’t changed one bit.
True, but this only prevents against stuff executing itself.
Mandatory access controls and sandboxes only protect the core system. Like installing packages with root.
You put things there privileged, so you know what you run comes from a protected area.
Running things from random directories (like
~/Applicationswhich AppimagePool uses) destroys that.Suddenly you rely on an executable home dir, which means any regular software (including appimages which are nearly impossible to sandbox) can write to the area where your programs are.
That concept is so broken that it needs to go.
I am against
flatpak install --userfor that reason, because no program should come from an unprivileged directory.The issue especially is if it doesnt follow standards.
~/.local/binis a standard, and with SELinux confined users you may be able to protect that directory. But random ones like~/Applicationsthat dont follow any standards, will not work.The “open with” and “create new” things. Actually,
Flatpaks cannot create “create new” entries too. I am currently experimenting with these, as it sucks to not be able to “create new Libreoffice writer document”. And the xdg-templates directory doesnt do anything lol, you still need desktop entries.
The concept of an installer is that the app does that on its own. That is pretty bad and the kind of Windows crap we absolutely dont want.
But on good operating systems, a privileged package manager does all that. Puts the stuff where it belongs. Flatpak for example links the desktop entry that the app itself contains in a sandboxed directory, to the export directory where the OS sees it.
And some portal or whatever deals with the “standard apps” stuff, like that Okular Flatpak will be shown to support opening PDFs.
If apps do this on their own that means a single app can mess up your entire system, also malicious.
Appimage may have tools, I only tried AppimagePool for curiosity and the experience was pretty bad and incomplete.
But the issue is that they were just thrown out there, “here devs, do the same shit you do on Windows, it is totally normal for people to double click an executable, not have any sandboxing, deal with updates on their own, dont have any cryptographic verification, …”.
And only afterwards came the managers, the daemons, which cover a part of it.
They (could) solve:
And they often dont even do that. There are no signatures, as devs were never told “either you add a signature, or people will not install your app”. So there is zero verification
But they dont solve the core issues that are:
Flatpak is similar to Android. On Android you still have a package manager but the APKs are signed individually, updates just allowed if the signatures match. So you can sideload how you want, it is still secure.
And using Obtainium, which is kind of like an AppimagePool, you can get all the apps from independend developers.
But they were told they need to follow all these rules, Appimage developers can do whatever they want.
Sorry that was long.
Regarding what? XD
~/Applicationsis no a random place, it comes from macos. And what is appimagepool?You mean appimagetool? that’s used to turn the AppDir into an appimage.
If you meant appimagelauncher,
~/Applicationsis the default location but it can be changed to any location.See that lock next to some appimages? Yes that’s aisap sandbox..
It isn’t perfect though, right now its biggest limitation is that a sandboxed appimage can’t launch another sandboxed appimage. But dbus, pipewire, vulkan, themes, etc works.
You can totally do that with appimages once they are integrated into the system by the previously mentioned tools, those menus rely on desktop entries in
$XDG_DATA_HOME/Applications.Good thing we have choices on linux, you can make your entire home not executable if you want to.
I like to keep all the software that I need in my home, because that way I don’t depend on what my distro provides. I can just drop my home anywhere (besides a musl distro) and I’m ready to go, I even have my window manager as an appimage because I couldn’t compile it statically.
AppImage is just a format, same as a deb or rpm, you decide how you handle it afterwards.
Same link again: https://github.com/AppImageCommunity/AppImageUpdate
Many of the appimage devs actually worked on making zsync2 for this: https://github.com/AppImageCommunity/zsync2
You mean the APK itself does the signature verification or what? With appimage it is AppImageUpdateTool that does the verification.
Again this nonsense.
You still have that github repo saying that appimages bloat the system when that is a total lie. they can even use less storage than native packages let alone comparing it to flatpak…
Hahaha I would call that VERY random. It is problematic that the default xdg directories are hidden.
And I just learned that you can just source scripts into bash and thus being executable or not doesnt matter. What an incredible design flaw… at least this just works with some binaries, I guess?
No the Flatpak Appimage Pool. But a solution to easily package a bunch of files sounds really awesome. I miss that for RPMs, sddm2rpm did this kind of.
Very interesting tool. So this is for appimages but also binaries?
I am a bit confused, especially as they state to prefer official releases, which for me means tarballs.
But a very good concept.
Interesting set of apps you have there. And ironically I have to agree they are small. Flatpak libraries are too huge and the deduplication doesnt work if it us not used for downloads and if there are dozens of runtimes.
A modular approach would be very much needed, instead of a damn KDE runtime that is nearly the entire desktop.
But I have some questions.
Thats not a sandbox, its a nice wrapper for firejail, at least what they write. I only knew some Github issue where they discussed this, and because Appimages require fuse they couldnt be sandboxed with bubblewrap.
Then they say “bubblewrap is used in Flatpak” but no comment if THEY also use it.
Firejail is the setuid binary I talked about, they likely have fixed their security issues but bubblewrap/bubblejail are probably better as they dont need setuid binaries.
If Appimages are possible to sandbox with bubblewrap, that would for sure be cool.
I also found rustysnakes crabjail, dont know the state it is in, but that is a possible candidate for replacing bubblejail.
No idea if Flatpaks can do that. But I would say the biggest issue is that the big vendors just put their appimage on some file server without any data on the sandbox.
Flatpak is way better here, where the sandbox is checked BEFORE apps are successfully submitted. And there are warnings etc.
And, of course, every app is sandboxed, not just a few.
Not the “create new” to my knowledge. That is in
$XDG_TEMPLATES_DIRbut I am currently struggling to make Flatpaks use that.Yes, so is Flatpak. But Appimages were introduced to be Windows-like. Sure there are companies that dont care and publish random rpms on their website too.
But with Appimages that is the only way as there is no real repo. AppMan is a cludge here, bundling together tons of different sources, kind of like Obtainium.
That tool is either completely finished or kind of abandoned.
Interesting, didnt know they have a signature builtin. That would also be useful.
That zsync2 thing explained in AppMan was just like delta updates. If a malicious actor has access to the old appimage and the fileserver, they can produce the correct zsync2 thing and the updates work, until signature verification is enforced.
As I said, as long as
bash script.shworks with nonexecutable stuff, noexec home is pretty worthless. Just another layer of defence.No, android APKs are like Distro packages, they can be sideloaded however you want and then are forwarded to the “session installer” (on modern android), which is the “package manager” of android.
That installer saves the signature somewhere, and from then on you can only update the APK if the signature was made with the same private key.
Found out you can also not sign APKs, which happened here. I honestly dont know if more developers dont sign their APKs.
I will update my repo text to get to the current state of facts.
I do mean downloading random stuff from random websites.
Hmm, is that a feature or a flaw?
A matter of perspective I think. It’s a flaw in my opinion. Just downloading anything from anywhere sets one up for failure/malware.
Code Signing on its own is useless, I think. If there is no distribution structure or user-validated trustchain, of course. But then you don’t really need Code Signing, a simple hash is enough.
My personal preference are the distro repos, to a point where I even dislike additional package managers like pip, npm or cargo.
Reducing the size of the OS helps a ton here.
And mounting home read-only. I think Android and ChromeOS do that. I will experiment with that too, it is really interesting. You mainly need a different place to store user scripts, and appimages are broken (how sad), the rest should be fine.
Then a few more core concepts help too:
Flatpak helps a ton centralizing the packaging efforts. And it works. There are tons of officially supported packages. And I guess many of them will be maintained upstream.
But you still have a secure system, sandboxing, verification and packagers that keep an eye on it, kind of.
On a secure system you would need to pay a lot of people, like the typical 3-5 people that package most apps. For doing security analyses, opting-in to every new update etc.
You have that option with the appimage, inkscape releases it themselves.
Thats how packaging works.
On Android I use Obtainium, as the package manager deals with signature verification. On Linux, Flatpak is the only equivalent to Android apps.
RustDesk is the only Flatpak not from Flathub I use, because they have messed up permissions.
There’s also Pied, which hasn’t gotten around to submitting to Flathub.
Wow, cool app!
That was my first thought upon finding it. It’s really hard to find though, even if you know the name of it.
Keep in mind the Rustdesk flatpak has full access to your machine and isn’t sandboxed
Yes true, thats why it is not published on Flathub.
I will add an override to it that makes sense.
Yeah I don’t trust it. Chinese made potential spyware
Lol
Because it is better?
