[SOLVED] Borken Package Manager - How do I fix this?

[crjackson]

I was installing a package when the computer locked up and the screen went rainbow colored.

After restarting I ran?

sudo apt-get install -f

it returned an error. Then I ran:

sudo dpkg --configure -a

it also returned an error. The same error was report when running both both commands. Please see the screen shot below.

I sure hope an re-install isn't needed. Thanks.

Please try:

sudo dpkg --clear-avail && sudo apt-get update

According to your original post, the error dpkg is encountering is a parse error in the file /var/dpkg/available. If directly going there from the terminal isn't working, I'd suggest trying to find it in Nautilus, there *should* be a folder at /var/dpkg, which has a file called "available" inside, which contains part of your dpkg configuration; dpkg is reporting there's an error at line 2.

Yes, please look at the screen shot. I did find the file and couldn't open it. It seems corrupted or something. I tried to open it using root privileges as well and got the same result as shown in the screen shot.

Awesome, that fixed it. Quick question though. If I had simply deleted the file and ran sudo apt-get update, would that have fixed it too...

[beno1990]

Try the following:



sudo rm /var/libs/dpkg/available && sudo mv /var/libs/dpkg/available-old /var/libs/dpkg/available


You should run a sudo apt-get update afterwards if it works.

Edit: oops, already fixed. :)

When asked, type your password fully and hit ENTER. You will not see it as you type.
