Since a few days ago everything was fine today I'm experiencing serious delays while connecting via SSH, either from network or USB-serial monitor. ssh verbose in the client hangs at "Entering interactive session" while at the same time in udoobuntu pops up "apt-check" using a lot of CPU. When "apt-check" dies ssh login is accomplished. this seems to be a famous ubuntu issue discussed from 2010 till these days so I suspect it's due to a broken update from trusty repo. Is anybody experiencing this?
