Trying to update from 16.04LTS to 18.04LTS but unmet perl dependencies or conflicts when updating packages

I've done: sudo apt update But when I do sudo apt upgrade, I get:

The following packages have unmet dependencies:
 perl-modules-5.22 : Conflicts: perl-modules
                     Conflicts: perl-modules:i386

I've tried:

sudo dpkg --configure -a

sudo apt-get -f install

sudo apt-get  install --reinstall perl-modules-5.22

sudo apt-get clean

Can't sudo do-release-upgrade until I get this fixed.

How do I resolve the perl conflicts?

Thanks!

Try uninstalling the `perl-modules` package, which was removed from Ubuntu sometime after 14.04.

It's hard to tell what's going on when you only give us bits and pieces of the output of your commands... Keep in mind that 16.04 doesn't get standard support and hasn't for over 6 months. That means it doesn't get updates and it also means that there is no longer a supported upgrade path. Theoretically you can sign up for ESM so you can get the updates you need to upgrade to 18.04, but this assumes the problem has to do with not getting updates and dependencies. The easiest/fastest/cleanest path forward is probably to install 18.04 cleanly. Don't wait until it goes EOL to upgrade.

Like @user535733 said, remove the perl-modules package. This will resolve the conflict and let you continue with the upgrade

@user535733: you're the man! it helped.

To be precise: you can't remove virtual package (which perl-modules are) - instead:

apt remove perl-modules-5.22

In my case.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
