Today, I have upgraded my Ubuntu 18.04 to 18.10. Before the upgrade, it has disabled the third party repositories, which is normal. After the successful upgrade, I was enabling one by one repo which is available for Cosmic. I have found no repo currently available for docker-ce, virtualbox, mkvtoolnix. So it is normal for them to be in Installed (local or obsolete) section of Synaptic.
But there are other software listed in this section for which I’m unable to find correct repo; also if I try to remove them, it is saying that it is going to remove other installed software.
Such as for libavcodec-extra57, it is asking to remove gimp. For libsnmp-base it is ubuntu-desktop. But neither gimp or ubuntu-desktop is in the same section.
Following is my /etc/apt/sources.list:
