Title:
Software Center has blank screen
Status in “software-center” package in Ubuntu:
Confirmed
Bug description:
When initially running Software Center all is OK but after I close it,
when rerunning it come up with a blank screen.
This all started when I upgraded to 12.04. It was OK with 11.10
I have done a complete removal, reboot and install form the package
manager but that made no difference.
If I type "killall software-center" in a terminal it will then run OK
but once again, after closing it will fail the next run.
If run from the terminal, after closing these errors are reported...
IOError: [Errno 5] Input/output error:
