Updating Ubuntu 22.04 LTS to 24.04.1 LTS and for some reason Nextcloud desktop client ran into issues while re-enabling the PPA for the new stable. It was easy to re-install / update the desktop client from https://launchpad.net/~nextcloud-devs
ppa except for one particular package:
Depends: libcloudproviders0 (>= 0.2.5) but it is not installable
Installed from a debian repo, but no idea why this package is not otherwise available in Ubuntu or the Nextcloud-dev ppa.
https://packages.debian.org/sid/amd64/libcloudproviders0/download
Manually installing this deb file resolved the issue. Placing here in case it helps anyone else. Cheers.
