I ran the program from the menu, then what ? I went to CLI and did apt-get install synaptic after that and got this
apt-get install synaptic
Reading Package Lists... Done
Building Dependency Tree... Done
Package synaptic has no available version, but exists in the database.
This typically means that the package was mentioned in a dependency and
never uploaded, has been obsoleted or is not available with the contents
of sources.list
E: Package synaptic has no installation candidate
What's the problem? What's going on. All I want to do in install synaptic.
