16.04LTS sudo apt upgrade fails

[Frank P]

When I try to run upgrade I get a series of errors. After a reboot, the first is shown below (captured with a redirect) It hangs at that point and has to be cancelled with a ctrl+z. The next retry results in a "run dpgk --configure -a" which hangs at the MySQL-server-5.7 I can add that code if it will help. Any suggestions appreciated.

Do you want to continue? [Y/n] Setting up mysql-server-5.7 (5.7.22-0ubuntu0.16.04.1) ...

Try running sudo apt install -f in a terminal.

Rebooted and reran it and got this



E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.


I've ran the "--configure" thing at least 25 times - after stopping services, after rebooting, etc, etc. It always fails
Any other suggestions
Thanks

Hello!

Telling us something failed 25 times gives us little of diagnostic value.

Would you please run the command and post the output?

Cheers!

output from sudo dpkg --configure -a
