[Ibrahim Njeru]

Public bug reported:

The error i got while updating from ubuntu 18 to 20:

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.
