View Full Version : [ubuntu] Can't upgrade 12.04 to 12.10 from local mirror

November 28th, 2012, 08:34 AM
Followed these steps for upgrading:
1. Updated the software list:

sudo apt-get update2. Upgraded current softwares (Just to be safe):

sudo apt-get upgrade3. Initialized the updater:

sudo update-manager -dAfter the updater gets necessary information I get this error on "Setting new software channels" stage:

Invalid package information
After updating your package information, the essential package 'ubuntu-minimal' could not be located. This may be because you have no official mirrors listed in your software sources, or because of excessive load on the mirror you are using. See /etc/apt/sources.list for the current list of configured software sources.
In the case of an overloaded mirror, you may want to try the upgrade again later.Additional information:
1. I am using a local mirror, http://mirror.dhakacom.com/ since the official mirror, http://bd.archive.ubuntu.com/ (CNAME of mirror.ispros.com.bd) is dead.
2. I disabled all the PPA from Synaptic, that is what I did when upgrading to 12.04 from 10.04.

What might be the problem? Or is there something wrong in the procedure?
