Please follow the below template, it will help us to help you!

Is this on Ubuntu 18.04.01 by chance?

[KingInTheNorth]

Yes it is Ubuntu 18.04.1 LTS

There is a known issue with this OS and its apt repositories not containing dialog or dhcp5 I believe a user in this thread managed to find a solution.

Okay thanks for the help!
