My upgrade using alternative iso from 11.10 to 12.04 got interrupted and I had to hard restart my machine. Now I feel that everything is recovered except my already installed packages like vim.
How do I backup my home folder for fresh installation of ubuntu?
Following are the errors I'm facing
I couldn't mark any
package for re-installation in synaptic or remove and install too. output of sudo apt-get install vim
Building dependency tree
Reading state information... Done
Package vim is not available, but is referred to by another
package.
This may mean that the
package is missing, has been obsoleted, or
is only available from another source
E:
Package 'vim' has no installation candidate
If I try installing it from synaptic I get
apache2.2-common:
Package apache2.2-common 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
my sources.list file
