When trying to install `zsh` got this warning about unmet dependencies:
```
The following packages have unmet dependencies:
zsh : Depends: zsh-common (= 5.8-6) but 5.8-6+deb11u1 is to be installed
E: Unable to correct problems, you have held broken packages.
```
This seems to have originated from an update from the `byzantium-security`.
unfortunately this update caused some Librem 5/zsh user end up with a non usable shell.
