Bug Report: AppRun inside AppImage is missing permissions

[Benji377]

I am trying to upload the AppImage packaged with cargo-packager to the AppImage store. They have a test pipeline that runs on every submission and makes sure that the AppImage is correct.

My AppImage passes all tests, but then fails to execute with the error:

/bin/bash: line 1: /run/firejail/appimage/AppRun: Permission denied

After inspecting the AppImage by mounting it and opening it:

./tooka_1.0.2_x86_64.AppImage --appimage-mount
cd /tmp/.mount_tooka

I saw that the AppRun directory was missing the executable permissions:

> ls
AppRun  tooka.desktop  tooka.png  tooka.svg  usr
> ls -l
total 31
-rwxr--r-- 1 root root 31552 11 giu 19.53 AppRun
-rw-r--r-- 1 root root   216 11 giu 19.53 tooka.desktop
lrwxrwxrwx 1 root root    46 11 giu 19.53 tooka.png -> usr/share/icons/hicolor/500x500/apps/tooka.png
lrwxrwxrwx 1 root root    47 11 giu 19.53 tooka.svg -> usr/share/icons/hicolor/scalable/apps/tooka.svg
drwxr-xr-x 6 root root     0 11 giu 19.53 usr
!w /tmp/.mount_tooka_e7qH04

Well, never mind. I just changed the cargo-packager code to make it executable, but the issue persists. I also noticed that I can execute both the before-chmod and after-chmod AppImage without any issues.
So as far as I am concerned, the issue is elsewhere
