as stated in the title, I’m having problems upgrading from 18.04 to 20.04.
After performing sudo do-release-upgrade I get
Fetching Fetched 0 B in 0s (0 B/s) Upgrading Fetched 0 B in 0s (0 B/s) Exception during pm.DoInstall(): E:Sub-process dpkg --set-selections returned an error code (100), E:Couldn't record the approved state changes as dpkg selection states Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg --configure -a). Upgrade infeasible The upgrade could not be completed, there were errors during the upgrade process. Restoring original system state Aborting Reading package lists... Done Building dependency tree Reading state information... Done
I have tried a number of solutions I found on the internet such as reinstalling different versions of dpkg, but most of the solutions seem to pertain to error code 1, not 100.
Any help would be greatly appreciated.
