View Full Version : [ubuntu] Dependency Problems when upgrading!

July 13th, 2009, 06:00 AM
Help! I tried to upgrade from 7.10 to 8.04 (to get current and possibly upgrade even further), but I keep running into an error while trying to configure libpam-runtime. Here's the output from sudo apt-get -f install:

It always hangs on that "md5sum: not found", and my entire distro upgrade is hosed. This is a production web server, so I can't just wipe it clean and install the latest version from scratch. How do I resolve the dependency issue?

Hi, try reinstalling the libpam-runtime package.

sudo apt-get --reinstall install libpam-runtime
sudo apt-get -f install

It's gotten worse. apt-get won't work, because it can't connect to the internet.

Yesterday, I tried to upgrade from 7.10 to 8.04 following these steps:
1) I added the old-releases repositories to /etc/apt/sources.list
2) sudo apt-get update
3) sudo apt-get install update-manager-core
4) sudo do-release-upgrade

The installation hung while installing libpam_rumtime, saying that no MD5 was found.

Since then, I haven't been able to SSH into the server, and I can't ping it, either. It seems there's a problem with the network interfaces. I disabled the firewall, but I'm still not able to connect to the server. I checked /etc/resolv.conf, and the only entry there was: nameserver
I need help checking the other network interfaces.

If we can't fix this installation, I'm happy to ditch it and start from scratch with a new one, but I need to know how to get the data off. Thanks for your help!
