Package: x2goserver When I try to install x2goserver from x2go ppa on my ubuntu trusty machine it fails: # apt-get install x2goserver Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. x2goagent : Depends: nxagent (>= 2:3.5.0.29-0~592~ubuntu14.04.1) Depends: nxagent (< 2:3.5.0.29-0~592~ubuntu14.04.1.1) E: Unable to correct problems, you have held broken packages. It seems that the recent upgrade of nx-libs on ppa to 3.5.0.29 version is the root of the problem. I am using Ubuntu 14.04.2 LTS, kernel 3.13.0-43-generic Best regards Luis Lucas
