Installing fetchmail - Not found in current repositories

**Background** This is probably very basic for someone, but I can not figure this out for the life of me. I wish to simply install fetchmail onto my raspberry pi. Using the command sudo apt-get install fetchmail results in the following: **What I have tried** I have tried sudo apt-get update which goes through the process of updating, then follow with the install command for fetchmail shown above, but the same result. Per fetchmail's own page it states that the sources are also available at two repositories: https://gitlab.com/fetchmail/fetchmail and https://sourceforge.net/p/fetchmail/git/ I am not very experienced at adding repositories as my attempts have failed. I did take a look at /etc/apt/sources.list and tried to mimic the one found in here but it just results in errors for me. I know this is probably very basic for most, but I really can't figure this out so much appreaciated!
