[Rustington] Updating Mint?

Tue Apr 24 09:31:26 UTC 2018

I haven't used mint a lot. I gave up on it a few years ago because it
didn't update well at that time. A fresh install ought to sort it out but
you would want to save any data first which can be done from a live disk or
stick if the system is too unwell for normal means. Harder is a list of
installed programs which can be made with a command that creates a list
that can be fed back to reinstall them on the new system if repositories
and versions permit.

The *ps* command is useful to tell you about running processes ( I often
use *ps -ef|less* or *ps -ef|grep "whatImlookingfor"*), but to find the
resource hungry ones I use the *top* command. Here is some output from my
system:

The CPU and MEM columns may help you find the miscreant so you can
experiment further.
