does not update with software center that crashes when opening

[Eric]

can update and upgrade through the terminal but not with the software center which crashes as soon as open.
This is probably due to shutting down the computer while downloading through the software center.
Thanks.

Using: Ubuntu Wily Werewolf (development branch) 15.10

When I enter:apt-cache policy pkgname, it says: unable to locate package name

None of the attached files mention software-center at all.

At a terminal, please enter "software-center" (without quotes), wait for it to crash, then copy and paste all the terminal output into this bug report. Thanks.

The issue has changed now, sorry

Your new issue still does not seem to be caused by software-center, especially since it isn't even installed.
