Title: Today's update killed my server
Post by: ocdpfsas on March 12, 2013, 08:00:55 pm
I've been running Zentyal Community with the latest updates as a PDC for my company for a few weeks and noticed an update this morning. I went ahead an issued an apt-get dist-upgrade and after it finished, DNS stopped working. I couldn't get any nodes on the network to access the internet while using Zentyal as the primary DNS. I then rebooted the server and it's been stuck on the initial loading screen ever since.

I tried rebooting a few times and went into recovery mode but over the past 10 years that I've been using Linux, my biggest frustration has been when it just won't boot. I simply don't know what to do...

I have reconfigured my router to take care of the issue with the network access but I really need to get this server back up and running. I do have a configuration backup so I could reinstall but I made a lot of remote changes such as Group Policy that I'm not sure will come back properly.

Please help! I'm not a Linux noob but I just don't know what to do at this point other than reinstall. Also, if anyone has any recommendations as far as applying dist-updates for Zentyal, I'm all ears.

Thanks!

What I would suggest is to not (never) run apt-get dist-upgrade.

BTW, what's your goal with such command ?

Can you start it in single user/emergency mode?


PS: ubuntu/debian default upgrade command is apt-get dist-upgrade. Why are you saying that it is a dangerous command?

Default command is apt-get update followed by apt-get upgrade
with dist-upgrade you are also upgrading from the current version Ex 12.04 to 12.10 and things tend to break when you issue such commands.

I would just suggest that using Zentyal's software management tools is an option to doing updates at the command line at all. That route serves as a reminder that there is no true distribution upgrade for Zentyal.

I updated with dist-upgrade following the Zentyal update documentation (http://trac.zentyal.org/wiki/Documentation/Community/Updates)

Regardless, I still need to get this back up and running. I can get to the terminal through recovery mode and can get SSH access while the boot hangs but I don't know what to do to attempt to roll it back or find the problem.

Other than reinstalling, do you guys have any recommendations?

Thanks again

Thank you for pointing out what the documentation is saying. I continue to think that that's bad advice and will see if it can be changed.

There is no rollback capability in Ubuntu that I know of. To my knowledge you would have to "force" apt to install certain package versions only if there is any hope of restoring things to a normal state, and my apt skills are inadequate for that. Hopefully someone else can offer better help. :-[

Thanks for the message. Yeah I figured there wouldn't be a simple rollback solution... I guess I'll have to reinstall. Luckily I do have the configuration backup but I have a feeling I'm going to have to redo a bunch of stuff.
