I have the same problem with slackware 15.0

[jfbauer432]

Same issue on Ubuntu 24.04

[alsternerd]

Same on Arch Linux.

[lukasmatena]

There are two AppImages in the release page, you need to download the other one. I have just amended the release notes with a paragraph describing the situation.

[juckendesAuge]

Thank you very much

But the name Ubuntu is a bad choice if it is to be used on several distributions. For this reason, I have not even tried to test the version...
It only refers to one Linux (Ubuntu) distribution.

It's the same with the version stated in the title, not just the Ubuntu-version.

On what system did you test the .AppImages before releasing?
Since libwebkit2gtk isn't even a package available in pacman on Arch. Haven't tested on Debian (stable and testing), yet.

[lukasmatena]

Thanks for your comments. I understand that the situation is not ideal and that there is room for improvement.

But the name Ubuntu is a bad choice if it is to be used on several distributions.

I understand. However, listing all distributions in the name would not be better, not to mention impossible. A suffix like "Ubuntu-24-04_Fedora-40_Slackware-15_..." did not sound right either. The "Ubuntu-24-04" was supposed to mean that the binary was built on Ubuntu 24.04. We briefly considered some "old" / "new", but that would probably raise even more questions as to what new features there are, etc.

We will spend some more time trying to build the AppImage that just runs everywhere. If we do not succeed, we may reconsider if AppImage is a good format to use for PrusaSlicer deployment... And if not, what is.

The .AppImage format is okay and better than snap or something like that.
But what can be done immediately is state the dependencies, in this case >= libwebkit2gtk-4.0 could be enough.
Maybe even in the Updatedownloader inside the PrusaSlicer.AppImage, so that we don't run into that after the update. :)

[Drezir]

What about flatpak? Is it an option to pack prusaslicer?

[neclimdul]

I don't know if its new but there's a separate appimage for these distros to fix this. It worked great for me.

PrusaSlicer-2.8.0+linux-x64-GTK3-202406271021-Ubuntu-24-04.AppImage

BTW, Thanks Prusa! Orca's been broken by this for quite a while now but you've already worked around it.

[skint007]

I get this error when installing the one for Ubuntu 24.04, which I'm on, if I run the none Ubuntu one, it just closes out instantly after running.

[nekopep]

Under debian 12 we have:
/usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.1.so.0
instead of 4.0.so

[abatkin]

The ubuntu version works if you create your own .desktop file, the appimage is not compatible with "appimagelauncher"

You don't even need to create your own .desktop file - launch it once (i.e. via a terminal) and let it do its own desktop integration.

Neither appimage works in Debian 12 (bookworm).

PrusaSlicer-2.8.0+linux-x64-GTK3-202406270929.AppImage doesn't work with the system libwebkit2gtk
PrusaSlicer-2.8.0+linux-x64-GTK3-202406271021-Ubuntu-24-04.AppImage doesn't work with the system glibc

I tried using flatpak, but the entrance script for that isn't reading from the xdg doc mount. The files are placed there correctly and if I launch it on its own I can open a file from there, but it's not launching properly when launched from a file.

Doesn't seem to be a working installation option for Debian at the moment

[juckendesAuge]

Still not working on Fedora 40

Flatpak works fine under Fedora

I think on debian 12 asking for libwebkit2gtk-4.1 will do the job

[transplier]

Please note that on at least my Kubuntu 24.04 installation, libwebkit2gtk was not bundled at all, which led to neither AppImage starting at all. I had to do sudo apt install libwebkit2gtk-4.1-0 to get it working. May be worth adding to the documentation, too. This information is included in the "how to build" section, but most users will not be building this software.

[flux242]

Both versions of the Appimage (Ubuntu and sansUbuntu) won't start on Ubuntu 22.04. Same error - missing libwebkit2gtk-4.1-0. I do not have that lib on my system at all! I carefully select what libs are allowed to be installed on my system and that lib does not belong

First of all creating different versions of AppImage defeats its purpose!
Secondly I don't really understand what's the problem of putting that lib into the container but instead starting to look for another container format! It worked before and now not? What is going on?

Ps: I checked there was no libwebkit in the 2.7.4 too. This dep must be something new
pps: I found this about libwebkit SoftFever/OrcaSlicer#4616 (comment)

thanks for adding this dep!

[frank-pian]

Orca tried to package libwebkit in the appimage, and the size of the appimage increased by 50MB, which seems to be acceptable.

But they didn't, choosing to do the same as prusa.

Confirmed on Debian bookworm (12.6) here - neither version works, with the same errors as @trainmeditations posted. This is definitely a packaging issue.

Following the build from source instructions, I'm able to build and run 2.8.0 on the same machine.

The ubuntu version works if you create your own .desktop file, the appimage is not compatible with "appimagelauncher"

You don't even need to create your own .desktop file - launch it once (i.e. via a terminal) and let it do its own desktop integration.

I have the exact same problem. Running 24.04 with appimagelauncher handling my appimage integrations. Can you give the specific CLI command to launch Prusa Slicer appimage bypassing appiamgelauncher? Uninstalling appiamgelauncher isn't really an option since it will break all my other appimage integrations. As of right now, I can't get Prusa Slicer to work at all on Ubuntu 24.04. Yes, I am using PrusaSlicer-2.8.0+linux-x64-GTK3-202406271021-Ubuntu-24-04.AppImage

[flux242]

Why do you need webkit? To render what's new page or to show ads? Can there be a version without that useful feature like before?

[neclimdul]

@flux242 it's used for the printer view where you can see klipper ui's and prusa's management site.

[VasilNikolov]

Can confirm debian doens't work even after installing libwebkit2gtk-4.1

[probonopd]

To everyone affected, please try the AppImage linked in

• 2.9.0-rc1 - AppImage #13653

and please let us know how how it works for you. Thanks!

[nekopep]

I confirm it works on debian 12! Good job!
