Now I don't understand Synaptic (Solved) On 20th July 2010 a.d. there was a security update 'libfreetype6' which for some reason I could not get, not even by manually updating. I switched to 'Main Server' and today got a whole raft of updates incl. the above plus grub etc. Now I see that all these updated packages are shown under 'Installed(local or obsolete)' whereas in the past only stuff not present in the official Ubuntu repos. were shown there. Does this mean I will in future not receive updates to those packages installed using the Main Server, or will Synaptic also check for updates to the packages shown under 'Installed(localor obsolete)' if they are from official Ubuntu repos. ? Edit: I see the packages are also shown under the 'Installed' section. Edit: An update using local server again solved the mystery - now only stuff I installed outside the official repos. is shown under 'Installed(local or obsolete)' as it should be.
