Since I had no answers writing in Portugese, I'll try to translate my problem to English.
I am trying to update the system and some apps via AppCenter (I guessing the name of the store like application, since my system language is Portuguese) but every time I got the same answer:
"Waiting for the package manager block" (trying to translate the message).
And then I can't update anything, neither the system or the apps.
This happened after I tried to install the latest updates but it was taking a very long time to finish (like 2 hours) and then I had to shut down the computer, but I couldn't because of the updating process. So I had to force shut down. After that, I always get this message when I try to install any update.
Can anyone please help me?
Thanks!
