pardus upgrade failed, pisi fails to start.
i did an upgrade from pardus 2009 to 2009.1
when all the packages finished downloading and started installing, the power went off suddenly.
Now my system is boots fine till the graphical login, but after i enter username and password, desktop fails to load and i am back at the login screen.
I tried to resume the upgrade using
# pisi upgrade
but pisi terminates after checking the repositories.
what to do?
