Last Friday, I was using software updater to update some of my software, but halfway through, I realized I wouldn't have time to complete all of the updates. I unfortunately had to stop the updates halfway through, and then tried to shut down. However, when I tried to shut down, the dialog box for shut down wasn't able to be clicked, and after trying several things, I was forced to do a hard shut down.
Turning my computer on today, I was greeted with several "System Program Problem Detected" dialog boxes dancing around on the screen. They prompted me to report the problems, which I did. But now everything is messed up! There are no visible internet connections for me to connect to, the software updater closes automatically whenever I try to install updates, and I can't turn off my computer (whenever I click shut down, only the dialog box for logging out appears.) I don't know what happened, but I'm really concerned. Things I have tried so far:
sudo dpkg --configure -a
Which seemed to resolve some issues, but not all. Then I tried:
sudo apt-get install -f
Which tells me it it unable to fetch some archives, and I should try:
sudo apt-get update
sudo apt-get update --fix-missing
Neither of which seem to resolve any issues.
Please, if you know anything about what might be going on, I would really appreciate the help.
