Computer (laptop) slows down or freezes. The update manager cannot be read.

sudo cp -arf /var/lib/dpkg /var/lib/dpkg.backup
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
sudo cp /var/lib/dpkg/available-old /var/lib/dpkg/available
sudo rm -rf /var/lib/dpkg/updates/*
sudo rm -rf /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update
sudo dpkg --clear-avail
sudo dpkg --configure -a
sudo apt-get install -f
sudo apt-get update
sudo apt-get dist-upgrade

May help

That was - almost - a home run. Went fine and downloaded packages. I'm a
complete newcomer to Linux/Ubuntu, so thats amazing. Unfortunately it went
wrong when I wrote 'sudo dpkg --clear-avail'. It said (in Danish):
'conflicting actions -l (--list) and -c -- actions)' I was suggested
'dselect' or 'aptitude', but neither worked. maybe I write commands wrong,
but tried both with '-' and without '-'. It also said that choises marked
[*] would give too many out-data and it should be led through 'less' or
'more', but I don't know what that means or how to do.

sincerely

John

Ok just skip that line and go to the next :)

Hey, i tried the Update pull-down menu, and it worked. Just restarted the
computer and apparently it solved the problem. Should I repeat the other
lines?

The problems seems solved. downloaded packages. Stopped at the line: 'sudo dpkg --clear-avail', but then the update manager worked from the pull down menu.
