Due to Centos is about EOL. I decided to migrate to AlmaLinux. I started the migration process but I got some errors.

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

I know that it's not possible to install two packages at the same time. So, I tried to remove the old one but it says that I'm trying to remove a private package (sudo) !!

I tried to downgrade/upgrade each package of the mentioned packages in the errors above but nothing changed! Then I googled for that issue but it seems that there's no further information about this issue.

Anyone can help please? Thanks.

You should follow each of the three suggestions that it gave you, one at a time.

@MichaelHampton, I tried but as I mentioned before, this didn't solve the issue.

You should add the output to your question, then.

@MichaelHampton, I already added it sir. I tried to upgrade/remove/downgrade the mentioned packages then I run the command above then I get the same outputs.

No, you did not. You were advised to try all three suggestions given to you above: `(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)`. There is no output corresponding to any of these three in your question.

These also hasn't solve the issue. They skip the conflicts only.

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.
