The APT Database could not be opened!

[aflebron]

When I try to run adept this is the message I got: "The APT Database could not be opened! This may be caused by incorrect APT configuration or some similar problem. Try running apt-setup and apt-get update in terminal and see if it helps to resolve the problem." I'm new to linux and I admit it was my fault 'cause I was trying to add programs to my repos. Please help!!!

Re: The APT Database could not be opened!

Did you try

sudo apt-get update

apt-setup isn't really for Ubuntu it seems. Reading on it it's just a graphical way to edit your /etc/apt/sources.list file

What could do is make sure adept, kmenu and everything else involved with installing  programs is closed.

Backup the original file first.  Open the Konsole (Kmenu>System>Konsole (Terminal program) then type in:

sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

enter your password. Then

kdesu kate /etc/apt/sources.list

You'll get a bunch of junk about how it's not working (ignore it when it does this), then it will ask for your password. After you enter your pasword your file will open.

This is the content of my sources.list file - if you want you can just delete what you have and paste mine in.

Click the save button and exit kate.

I can't remember if this is one of those reboot things or not, so I'd suggest rebooting here. Then reopen a Konsole and enter

apt-get update

Hope this helps - it can't hurt. :-) If worse comes to worse just  cp the sources.list_backup back to sources.list
