package gdm 2.30.2.is.2.30.0-0ubuntu5.2 failed to install/upgrade: subprocess installed post-removal script returned error exit status 1

I don't know what's happening.

It all started because alacarte wouldn't work, from the terminal, or right clicking the menu and clicking "edit menus." Root user couldn't do it, either.

So I tried purging alacarte, restarting, and reinstalling: same problem

after reinstalling ubuntu-desktop et-al, I got the error that I'm sending attached.

here's my what comes out in terminal when I try alacarte:

jordan@jordan-AOA150:~$ alacarte
