System dead after update and reboot

  • 772

So I rebooted my system after an update and upgrade. Now my raid is missing, all of my network settings, programs, etc are "missing" I think they are all in the missing raid. I have to use ip to add an ip and dgw before the system will come online. My username doesn't seem to exist anymore so I have to use root to sign in. My home directory is in the raid for sure.

Not really sure what else to say. When I try to install software I get error status 1 with no real output. I didn't see anything helpful in the logs. Any ideas? I have literally my whole life of files on there (7TB) so I'd rather not lose them if I can help it. That's all I really care about.

Ubuntu server latest lts,

Any help is greatly appreciated!

update

I have gotten my profile back now and the raid is assembling and mounting. I can connect to the net by using dhclient -r && dhclient

now when I try to update I get

Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/lib/command-not-found/ -a -e /usr/lib/cnf-update-db; then /usr/lib/cnf-update-db > /dev/null; fi'

update

Went into tty mode and force removed python, left tty and ran dpkg --configure -a (no errors) then I ran update but got a python error. Installed python again and updated, had 900+ packages that need updates now (they didn't before all this) and so far they have been running alright.

However; I did get this message and I assume it has something to do with the root cause.

  1. First of all try to reconfigure the installed packages with

    • sudo dpkg --configure -a

    Check if the user still exist with something like

    • awk -F: '{ print $1}' /etc/passwd And check your files
    • ls /home/$USER (write your username if your are connected with root)

    Check the network settings in the file /etc/networks/interfaces. If it doesn't exist create one from an internet sample and run:

    • sudo systemctl start networking
