When I install a new package, I get these error messages:

$ sudo apt-get install jetty
Reading package lists... Done
Building dependency tree       
Reading state information... Done
jetty is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 198 not upgraded.

After this operation, 0 B of additional disk space will be used.

And I do not know how to fix it.

  • What's your Ubuntu release? Your third-party Ruby package from a PPA is incompatible with a different Ruby package provided by Canonical. You can either use the ruby package or, if you need the v1.9 branch, save yourself the headache and use rvm to install and manage different Ruby versions. See How do I install ruby-rvm? and specifically this answer. – David Foerster Feb 06 '17 at 18:55
