Describe the bug

Different from the previously reported issue (#1360) being valid til 0.25.3, the AppImage version of 0.25.4 returns via shell the error message APPRUN_ERROR: No such file or directory and ends.

For comparison, Saber-0.24.6-x86_64.AppImage still runs. I noted also that Saber-0.25.4-x86_64.AppImage is only 87.6 MB while Saber-0.25.3-x86_64.AppImage is 131.9 MB (and before similar) - maybe something missing?

To reproduce

1. Download latest AppImage file.
2. Open shell.
3. Execute Saber-0.25.4-x86_64.AppImage.
4. See error message.

Expected behavior

Start of Saber - last possible with Saber-0.24.6-x86_64.AppImage due to earlier issue #1360.

Saber version

Saber-0.25.4-x86_64

Device

• Device: Intel NUC8 i5
• OS: Linux Mint 22.1

Anything else?

Please have a look into this and #1360. Thank you for all the hard work!

Same here on PineNote running Debian Trixie

I'm having this same issue. Can't update from the appimage due to the APPRUN_ERROR: No such file or directory issue in CLI.

I can confirm that this issue is still present in version 0.25.5 (as of 2025-04-18, running on Debian GNU/Linux 12 Bookworm):

$ ./Saber-0.25.5-x86_64.AppImage 
APPRUN_ERROR: No such file or directory

at least on my system:

$ uname -a
Linux 6.1.0-32-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.129-1 (2025-03-06) x86_64 GNU/Linux
$ cat /etc/issue
Debian GNU/Linux 12 \n \l

Can confirm that the issue persists also with my installation (Linux Mint 22.1 Xia 6.8.0-58-generic) in 0.25.5.

I upgraded to Debian 13 Trixie and Saber 0.25.6-x86_64, since I read that this type of error is most likely due to an incompatible version of libc.

Saber still won't start, but the APPRUN_ERROR: No such file or directory is gone. Instead, the error message now reads:

/tmp/.mount_Saber-7VNM14/saber: symbol lookup error: /lib/x86_64-linux-gnu/libgstaudio-1.0.so.0: undefined symbol: g_sort_array

@dingodoppelt, can you confirm?

For me, the issue with APPRUN_ERROR: No such file or directory persists also with the latest update to 0.25.8 - no change.

[jsghjsgh]

Issue persists also with 0.26.0.

Issue APPRUN_ERROR: No such file or directory persists also with latest 0.26.7 release. I read in the changelog "Switched the AppImage to use zstd instead of xz compression, [...]" and had some faint hope but no ...
