16.04 upgrade interrupted, now in all sorts of trouble.

[pnunn]

Hi Guys,

due to a power failure part way through a 16.04 upgrade I now have a machine half installed and am in a world of pain.

When I do apt-get update -f now I get 620 packages not fully installed or removed and when I continue I get lots of errors and eventually a long long list of packages with Processing was halted because there were too many errors.

I've tried dpkg --configure -a and some of the packages seem to install OK, but now I'm getting lots that say

Am I totally screwed? Is there a way out (I need to atleast get mysql data out of my databases).

Thanks

pnunn; Ouch !!

Maybe- just a maybe ;
Clean out the old packaging files and try to get anew; and clean up the mess ---- maybe .
Try :


sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get clean
sudo apt update
sudo apt-get dist-upgrade --fix-missing
sudo apt-get dist-upgrade --fix-broken
sudo apt full-upgrade
sudo apt -f install
dpkg --configure -a
where there are some duplications of commands, the hope here is that the new apt may be more able to handle what apt-get does not.
We try and stay within the package management system .




maybe YES

You suffered a power loss at the worst possible time.
Ubuntu is vulnerable and cannot be easily recovered if power is lost during the few minutes of a release-upgrade.
You may recall the warning about that when you began the upgrade process.

My suggestion for the easiest and fastest way to recover for most users:
1) Download a fresh install .iso of Ubuntu 16.04 from downloads.ubuntu.com
2) Use the .iso to create an Install USB
3) Boot from the USB, mount your hard drive, and backup all your data to some external media...including your SQL databases.
4) Overwrite your old, corrupted 16.04 with a fresh install.
5) If needed, restore your data from the backup.

Ubuntu is very good about not overwriting data in /home. I don't know where you chose to put your databases, and a backup surely cannot hurt...just in case you decide to format the entire disk.

Thanks for the help guys. After 24 hours that I'll never get back again I think I'm pretty much back to running.

To get here I had to remove a couple of packages (apt purge) that were causing issues (aiccu, mongod and pdns) and run dpkg -config -a several times fixing this as I went.

It took AGES to work out why my web sites were still hosed but that turned out to be a combination of ISP blocking ports that I wasn't aware of (having just changed providers), ownership of .htaccess files and for some reason the document root changing to /var/www/html and totally ignoring any attempt I made to change it back to /var/www

Just need to get pdns working again and we should be all good hopefully.

Thanks for the input. Greatly appreciated.
