Comment 3 for bug 63777

Eh, today I fought quite a long time with synaptic to get it to unlock some packages : no way. Synaptic did as it does when it does something, but when I got hand again, nothing had changed.

I finally unlocked them by removing the /var/lib/synaptic/preferences file (which had been created when the box was still dapper).

I then changed my mind and decided to re-lock one of them. Same problem.

I would say the menu is connected to "make the user wait while we rebuild the package categories which we didn't change".

Hope it helps
