Title:
Bwrap: Creating new namespace failed
Status in bubblewrap package in Ubuntu:
Confirmed
Bug description:
I have installed Cryptopmator app via Flathub and try to run it:
`flatpak run org.cryptomator.Cryptomator`
It does not run, and I get the error:
```
bwrap: Creating new namespace failed: Permission denied
error: ldconfig failed, exit status 256
```
My system is Ubuntu 24.04.1 and `cat
/proc/sys/kernel/unprivileged_userns_clone` says `1`
The solution is:
```
sudo chmod u+s $(which bwrap)
```
However, this makes the bubblewrap binary SUID, by default it is
supposed to work with unprivileged user namespaces. This is most
likely due to Ubuntu doing some kernel and apparmor related changes
that landed in 24.04.
