Be aware that updating to 24.04 deleted my Next Cloud client that was installed from the Software Boutique. I don't know if it will affect the client if it was a snap.
This resulted in me having to install the snap version. I had trouble trying to figure out how to sync the local files to the server. It's confusing so I borked the sync and had to do a fresh sync to the server. Basically erase the local Nextcloud directory and rebuild it. I mistakenly lost some work in the process. Stuff happens.
