Mono 3.2.8 on SEL

See here if your SEL is still on mono 3.2.8 and you are trying to get to mono 5.

SSH ONLY and on Systems with 3.2.8 where original Mono 5 SEL script is not working

Backup your system before making any changes in the Linux OS.

Login with root

cd /etc/apt/lists/sources.d

nano sources.list to find out which version of Lubuntu. It will be repeated toward the end of each source line (usually trusty) then exit

EXAMPLE (oneiric repeats)

cd /etc/apt/lists/sources.list.d

There should be a mono sources list file in here

Nano that file and it should contain something like "deb VERSION main" (VERSION could be wheezy, trusty, bionic, oneiric or something else)

Make sure VERSION matches what was repeated in the sources.list and add "-stable"

EXAMPLE "deb trusty-stable main"

Save and Exit

Now run apt-get update and apt-get upgrade.

If upgrade is not working/completing, you can run apt-get dist-upgrade. The overall upgrade should take 5-10 minutes. You will see mono 5.XX in the file names as it unpacks and installs.

Users may have to fix some broken events after as this is a big upgrade.
