Edit: I wanted to add a note that after chasing my tail on this for a while, and encountering/creating various other problems, I ended up just starting over with a clean install.
I'm running into an error that I'm hoping someone can help me with.
Whenever I try to add a shared folder, I get the following error:
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; systemctl restart 'sharedfolders-AppData.mount' 2>&1' with exit code '1': Assertion failed on job for sharedfolders-AppData.mount.
In case it's helpful, I'm in the process of migrating from a Raspberry Pi-based installation to an amd64-based install. I'm moving my data drives from the Pi to the new server, and this is an error that's popping up as soon as I try to create the shares on the new machine. Perhaps it's also noteworthy that when I try to create shares from a drive that was never connected to the Pi, I get the same type of error.
Thanks a lot for any help!
