Dear professional collegues, Do anyone using Ubuntu 9.10 (Karmic Koala)? It is working fine except its latest update manager. I could not able to update 9.10 to 10.04 LTS because its install button is not activated which is supposed to. Even I could not able to install few required software. It's software source download server is not pining from any server. When checking its update manager showing "an error occurred" with following details.
