I did a fresh install of ubuntu 12.04 over my earlier 11.10.I saved the sources.list from my previous installation to another partition and replaced the sources.list in /etc/apt/ of the current installation with it,after editing it for the new distro.I got a lot of errors while using update manager so I deleted the sources.list.
At the same time,I was installing a lot of packages from synaptic manager and I left the download and install for the night(my Internet connection speed is just 256Kbps). Now,I cant find any of those packages like chromium,wine and javacc installed on my computer!Even in synaptic the packages are shown as not installed.Please help me out,I cant start another download and wait for 6 hours.
