It's not clear what instructions you followed to install vscodium - but it appears to require a gitlab repository.
The vscodium developer github page suggests that any problems need to be directed at gitlab.
Any issues installing VSCodium using your package manager should be directed to that repository's issue tracker.
If the problem is still active and you cannot wait until it is sorted out, reversing the installation of the package may remove the gitlab paulcarroty repository and may allow the system to update/upgrade.
