[Bug 1874158] [NEW] Upgrading Ubuntu to version 18.04 Invalid package information

[Gared.Herdrichsen@sapo.pt]

Public bug reported:

Upgrading Ubuntu to version 18.04

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.
