    update killed system

    Hi All,

    I'm running kubuntu 20.04. Yesterday a bunch of system updates came in. Seemed like the usual stuff, so I let them install. It took a little longer than usual, but there were quite a few, so I just let it do its thing. After they completed it notified me that it needed to do a reboot to complete the install. I did that and it took a long time. It was several minutes before I got back to the desktop. Even then it was very sluggish. Windows were only partially drawing, clicks didn't do anything, and so forth. There was no drive activity or network activity, or even CPU load beyond a regular idle state. After a few minutes I decided to try and reboot it again. This time it dumped me into the emergency mode and that's where it is now. I'm not sure what to do with it at this point. Any suggestions?

    (I was going to post this on the kubuntu forums, but they appear to be down. Wonder if the same issue hit them?)

    Thanks for any help you can offer.

    Sounds like a bad kernel update. When you reboot, hit esc, from the grub menu choose advanced options, it will list two kernel, boot into the previous kernel (the one with lower number) and see if it works. If it works, go to muon or synaptic to remove the new kernel stuffs (search for linux image and linux headers and uninstall everything with the highest number)

    make sure you use wired connection when updating. you can get corrupted package easily via Wi-fi.
    Read the easy to understand, lots of pics Ubuntu manual.
    Do i need antivirus/firewall in linux?
    Disk backup (works on newer PC): Clonezilla
    User friendly full disk backup Redobackup is now back as Rescuezilla

    ?? I always use only wifi, a lot of us in shared accommodation don't have access to wired connections (modem is upstairs, separate entrance) A wired connection to me is like cable TV, desktop computers, landline phones and Windows. Haven't used any of those for more than 10 years.

    If you boot an older kernel is it OK?

    I'm running Kubuntu 20.04 and have kernel 5.4.0-40-generic and as a backup 5.4.0-39-generic. A check for updates shows that -40 is the most recent kernel. No problems here for me.
    If you ask for help, do not abandon your request. Please have the courtesy to check for responses and thank the people who helped you.

    Looks like I have kernel versions 5.4.0-40, -39, -37, and -33. Tried them all. Get the same errors with all of them.

    No. Didn't work with any of them. Something else went sideways.
