Hi,
as i had some problems with LE i wanted to go back to Ubuntu Server version.
I downloaded the latest ubuntu-18.04.1 server iso and this one seems to lack some repositories.
Do i need to download another is or could you point me in right direction to get the repositories for below packages?
All other packages installed and distro-upgrade is OK ...

E: Package 'mesa-utils' has no installation candidate
E: Unable to locate package libmad0
E: Package 'lm-sensors' has no installation candidate
E: Unable to locate package libmpeg2-4
E: Package 'libnfs11' has no installation candidate
E: Package 'libva2' has no installation candidate
E: Unable to locate package vainfo
E: Package 'i965-va-driver' has no installation candidate
E: Package 'openbox' has no installation candidate

i fixed this by adding the repos from https://help.ubuntu.com/lts/serverguide/...on.html.en , strange that they were missing in /etc/apt/sources.list from the clean install of 18.04.1
