Using Linux Mint 20 Cinnamon
I have been unable to get the upgrades installed. After entering my password, the Error Message below appears.
I do not understand what it means, I have opened a Terminal and entered "dpkg --configure -a"
but the machine returns "command not recognised",
How do I proceed?
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.
