Cannot update to 19.04 -the essential package 'ubuntu-minimal' could not be located.
Hi there; I'm having a problem updating 2 droplets, one from 18.04, the other from 18.10. 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)"
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.
do-release-upgrade 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 This can happen if you run an internal mirror or if the mirror information is out of date.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.

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. Restoring original system state
