Q: I am missing two binary sources from the 'Other Software' list. Where have these binaries gone and how do I get them back? I have upgraded to Ubuntu 17.10 (artful) but have found that I am missing two binaries on the 'Other Software' list in the Software and Updates manager. Both the 'important security updates' (main restricted) and the 'recommended updates' (multiverse) binaries are missing and only the source code ones are there (and not ticked). I think these missing binaries should be there already, installed with the os (Ubuntu 17.10). How do I get them back? Would I be able to add these if I had the URIs for them?

Here is my log:
