Cannot Upgrade From 23.04 to 23.10

[mrkeef]

Whenever I try to upgrade from 23.04 to 23.10 I get this error:
Error during update

A problem occurred during the update. This is usually some sort of
network problem, please check your network connection and retry.

I don't have an internet problem. In fact, the upgrade process downloads stuff before it gets to this point.

I have tried both "Software Updater" and the CLI command sudo do-release-upgrade (with -d and -c ,not both at the same time)

Was this the first upgrade attempt? Are there other error messages?

That fixed "that" error, but you potentially have more errors to prevent.

Number 1 rule for PPA and Upgrading a release version is to disable your PPA's "before" you attempt a go-release-upgrade... From the output which I asked for, you still have many PPA, and external repo's to disable before you are ready for that...

The easiest way to do that, is to start up the "Software & Updates" app > Software tab > write down all the ones that are checked (currently)... Important. After you do that, uncheck them all.

Do your release upgrade.

After it is through... Start That app back up, and check those written down checkboxes again. Close the app.

Then open a terminal...

sudo apt update ## <--- Do not do the second command if you have errors with this
sudo apt upgrade

Check the output for errors... Why? >>> Because some PPA's and repo's may end at a certain release version, like where you were at before the release upgrade.

If you get an error with a message something like: "missing release file"... Then that is the case. Go back to that app, and uncheck the box for whatever that was. Wash, rinse, repeat until you have no errors.

The second command will see the release is newer, ad update the packages from that PPA or Repo.
