vlc: cannot start program (snap)

[Archangelll]

Running firejail vlc shows the following error:

Error: no suitable vlc executable found

[rusty-snake]

Is vlc installed? How did you installed firejail/vlc? In which distro? In which version? Does vlc work? Does firejail --noprofile vlc work? Do you have any modifications (e.g. globals.local)?

[Archangelll]

1. Yes
2. sudo apt install firejail/vlc
3. Ubuntu
4. 20.04
5. Yes
6. No
7. No

$ firejail --noprofile vlc

internal error, please report: running "vlc" failed: cannot create transient scope: DBus error "org.freedesktop.DBus.Error.InvalidArgs": [Process 2 is a kernel thread, refusing.]

Parent is shutting down, bye...

[rusty-snake]

4. I meant the firejail version
5. Bad. Is vlc the only program broken in firejail? Or is even something simple like firejail --noprofile true affected?

[Archangelll]

firejail version 0.9.62
As of now, only vlc

[rusty-snake]

Can you try with the noprofile.

[netblue30]

Added in noprofile.profile in git!

$ firejail --noprofile vlc

vlc is not written in Go, and "system_key.go" seems to be a snap thing.

So presumably vlc was installed as a snap, which is not supported by firejail.

Solution: Uninstall the snap and install the normal .deb package (or use an
AppImage).
