[SOLVED] 18.3 to 19 Upgrade Error

[GaryD]

Have you upgraded your Mint like the same route that I did?

Well, for me I followed this post:
https://community.linuxmint.com/tutorial/view/2416

Then run through this error, which prevented me from upgrading my system. Luckily, I got Time Shift installed, and got my system back in working condition in no time.

The error I encountered was:

Code: Select all

Processing was halted because there were too many errors. 
E: Sub-process /usr/bin/dpkg returned an error code (1)

I managed to save the logs, but was wiped out when I restore my system with Time Shift. My bad, I should have configured it prior to using it.

Will try to upgrade again today and save the logs.

Probably what you don't want to hear but a fresh install in the end will be less hassle and take less time. I have found pretty much the hard way that upgrades within versions tend to go smoothly whereas upgrades between versions tend to be problematic - I am a sample of one but that has been my experience in the five years I have been installing/upgrading Mint for myself/family/friends.

Did you use the command

Code: Select all

mintupgrade check

to run a simulated update? That usually show what needs to be done.
Run it after taking care of one of the problems it states, then re-run the command until there are no more errors reported.

Hello, GaryD.

Other users who upgraded from Mint 18.3 to Mint 19 in-place, following the official instruction just like you, have been hit by the same problem.
Please, find 2 threads, where users report which steps have worked for them to solve the problem and to complete mintupgrade successfully in the end:

Hi, JerryF.

"mintupgrade check" may succeed, nonetheless "mintupgrade upgrade" may abort with the reported error.
Obviously "mintupgrade check" does not detect the problem, because the root cause is only created by what "mintupgrade upgrade" does.
I vaguely remember having been in the same situation. [cf. here]

Cheers,
Karl

Thanks for posting that! I didn't know.

Success! Got it fixed by reseting system locales and dpkg configure.

Details:
As suggested by Karl, I've read from the Upgrade from Mint 18.3 to 19 failed and tried the suggested fix. On that topic, we have similar error during the upgrade.

Code: Select all

perl: warning: Setting locale failed.

The above error was fixed by doing (to reset locales):

Code: Select all

sudo dpkg-reconfigure locales
sudo update-locale LANG=en_US.UTF-8

Then the fix for the first error I posted above:

Code: Select all

sudo dpkg --configure -a

Then did:
mintupgrade upgrade

And it went all the way to:

Code: Select all

 + The upgrade is finished. Reboot the computer with "sudo reboot" when ready....

Upgrade done!

Thanks Karl! and the rest of the gang who tried to help.
