Why MySQL Repository Key suddenly expired?

14.04 apt mysql

Why is this happening? I've updated my machine last week.

  Thanks! But I've already purged MySQL and after some googling & struggling, purged all it's repos & GPG from apt.

  MySQL was on machine for more than one year. And suddenly at that time it got broken (not just me). But since I no longer use, I just purged it.

I had to use a different keyserver. sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 5072E1F5

The above comment is the correct answer.

Another automatic way is to refresh keys that are already present: sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --refresh-keys
