Impossible to start the application

[j75]

On Ubuntu 20.04 with a 5.8.0-45-generic kernel :

$ flatpak run de.haeckerfelix.Shortwave
bwrap: Creating new namespace failed: No space left on device
error: ldconfig failed, exit status 256

Any idea how to solve that?

I would suggest you start with emptying the wastebasket

What wastebasket? the "Bin" icon it is empty, and it is true:

% tree .local/share/Trash/
.local/share/Trash/

There's nothing inside! Also df -k . shows

[ZanderBrown]

It's somewhat expected that it fails to open non-existent files, things like /usr/share/locale/en_GB.utf8/LC_MESSAGES/libc.mo are rather unlikely to exist - that's just gettext following the rules and trying anyway

However /usr/share/locale/en_GB/LC_MESSAGES/libc.mo should (I just checked and it's in the runtime) - have you tried flatpak repair? Looks like you've corrupted something

PS: What Wastebasket? The Wastebasket

[j75]

No change after flatpak repair! :-( And as you can see from the attached snapshot;, my wastebasket ("the Bin!") is empty.

[haecker-felix]

This problem doesn't look like a Shortwave problem at all. Looks more like a problem with Flatpak itself. I have no idea what could cause this. I think you're going to have more success when you're asking the Flatpak folks directly.

[j75]

So basically when you don't have any idea of how to solve the issue, you close it! :-(

[ZanderBrown]

Well to be fair you reported this against @haecker-felix 's app and Felix doesn't have much interest/knowledge in lower-level stuff and this would seem like a broader flatpak issue better serviced by flatpak devs

[j75]

Well, I don't think the error related to @haecker-felix - it is simply caused by the max_user_namespaces kernel parameter:

$ cat /proc/sys/user/max_user_namespaces
46987

I think the previous value was 0 due to some security considerations on Debian/Ubuntu; setting it to a higher value solved the problem and now Shortwave starts.
