[Bug 1825938] Re: Cannot update to 19.04 ubuntu-minimal could not be located

[Jonathan H]

Note that in the error below, it complains about not being able to find
ubuntu-minimal, however, if I try and install it, it says:

"ubuntu-minimal is already the newest version (1.425.1)"

Also verified here: https://www.digitalocean.com/community/questions
/cannot-update-to-19-04-the-essential-package-ubuntu-minimal-could-not-
be-located-2

So might be an issue with Digitalocean VPS setup. Anway...


Here's a summary of the output - most of the stuff about "No valid mirror found" seems fairly standard on each update and hasn't been an issue before.

Updating repository information

No valid mirror found

While scanning your repository information no mirror entry for the
upgrade was found. This can happen if you run an internal mirror or
if the mirror information is out of date.

Do you want to rewrite your 'sources.list' file anyway? If you choose
'Yes' here it will update all 'cosmic' to 'disco' entries.
If you select 'No' the upgrade will cancel.

Invalid package information

After updating your package information, the essential package
'ubuntu-minimal' could not be located. This may be because you have
no official mirrors listed in your software sources, or because of
excessive load on the mirror you are using. See /etc/apt/sources.list
for the current list of configured software sources.
In the case of an overloaded mirror, you may want to try the upgrade
again later.
