This is not a simple disk space problem. I've started an upgrade of Ubuntu Studio 16.04 to 18.10, though ran into "no space left on disk" and it terminated with an error. I no longer can launch Thunar or Nemo to free up space as I get a "symbol lookup error" for each. df shows my drive has 0% available. Is there a way for me to recover from this and restart or resume the upgrade?
Update: I tried "sudo apt-get install -f" though that resulted in a "relocation error". I ran "dpkg --configure -a" and that mostly ran smoothly, though there were a number of dependencies that could not be resolved and were left unconfigured. The building of the initial module for 4.4.0-142 lowlatency succeeded. However, when attempting to generate /boot/initrd.img-4.4.0-142-lowlatency, "Errors were encountered while processing" and there was a list of about 30 packages that followed.
"sudo apt-get install -f" no longer runs as apt-get is unrecognized
"dpkg --configure -a" quickly resolves to the errors it ended with before.
"apt dist-upgrade" also fails with relocation error
"do-release-upgrade" exits with "Please install all available updates for your release before upgrading"
In the end, started all over, wiped the partitions and loaded Ubuntu Studio 18.04, and pulled in my backed up files with Back in Time.
