Is BFGMiner 5.4.2 available for Ubuntu 16.04 users?
I have a new install of Ubuntu 16.04.
Bitcoin Core 15.1
BFGMiner 5.2.0
I am trying to upgrade to 5.4.2 to see if will resolve an issue and when I use the command
apt-get install bfgminer
it says I am already at the latest version 5.2.0. I installed it only a week ago.
How do I get upgraded to 5.4.2 if it is available for Ubuntu?

Confession: I am a newly convert to Linux so go easy on me.
