How to refresh the list of updates?

[Brian Cluff]

Those 2 repositories are from get-deb and are probably not significant 
to the system.  My biggest concern is that they are pointing at an 
Ubuntu 14.04 repository....  Is your machine running Ubuntu 14.04?  If 
so, that version stopped being supported in 2019, unless you pay Ubuntu 
a subscription for extended support.  In any case that's probably not 
your main problem.

I don't like using any of the GUIs for big updates because they haven't 
been very good at handing odd problems and end up breaking your system 
when they don't know what to do, especially on the older versions of the 
distributions.

I'd do the upgrade from the command line and just do:
sudo apt-get update
sudo apt-get -f dist-upgrade

The update command will likely give you the same error about the getdeb 
packages.  You could comment those repositories out if the error is 
bugging you.
Upgrading from the command line will hopefully give you a nice human 
readable error that you will be able to handle and get the install to 
finish.
