Ubuntu Apt-get Update failed
1. Error occurred: E:could not get Lock/var/lib/apt/lists/lock-open (11:resource temporarily unavailable)
This problem may occur because another program is running, causing the resource to be locked out of service. The reason that the resource was locked may have been the last time that the installation was not completed properly, causing this condition to occur.
WORKAROUND: Delete all the files in the/var/lib/apt/lists
Enter the following command
sudo rm/var/cache/apt/archives/lock
sudo rm/var/lib/dpkg/lock
After installing the package you want to install, you can solve
2. Error occurred: E:some index files failed to download. They has been ignored, or old ones used instead.
Workaround:
To upgrade a really old Ubuntu release, we first need to edit our sources.list and change all (xx.) archive.ubuntu.com to old-releases.ubuntu.com.
$ sudo emacs/etc/apt/sources.list
So your lines should instead of
Deb Http://archive.ubuntu.com/ubuntu jaunty main restricted universe
Look like
Deb Http://old-releases.ubuntu.com/ubuntu jaunty main restricted universe
In the example I use jaunty release. But it works the same in other releases.
Now update the Repos
$ sudo apt-get update
