apt-get update (and apt update) command on my computer got very slow after upgrading to Ubuntu 19.04. There seems nothing wrong with the network since the downloads complete almost immediately. But the step after that (which does not print anything) takes incredibly long time (10 minutes or more). My hard drive seems working during that time.



enter image description here



I have cleared apt-get cache by both removing /var/apt/cache and using apt-get clear command but the problem persisted.



When I press Ctrl+C to end the process, the following message is printed out:



enter image description here



After seeing that message, I tried to execute apt-get update again and searched cnf-update-db in running processes.



enter image description here



There isn't a performance issue on my computer other than this one.



If I let the process complete once, it becomes faster in subsequent tries. But after some time, it becomes slow again.

It seems that your command-not-found package is corrupted somehow. You could purge it, remove its configuration, reinstall it and then reconfigure it as well as finally update it with:



sudo aptitude purge command-not-found
sudo aptitude purge ~c command-not-found
sudo aptitude install command-not-found
sudo dpkg-reconfigure command-not-found
sudo update-command-not-found


These are the files the command-not-found package contains: https://packages.ubuntu.com/en/disco/all/command-not-found/filelist



Good luck.

try running the following:

This might update any outdated versions that may be breaking apt update.



Also, try reinstalling python3:



sudo apt purge python3 && sudo apt autoremove && sudo apt install python3


Hopefully this works.

    Do not ever remove the preinstalled python or python3! (unless you really know what you're doing.) Many important packages depend on it and will stop working. Fixing this can be troublesome.

You should remove any old repositories from your computer.
Then run



sudo apt update && sudo apt autoremove


and then



sudo apt update && sudo apt upgrade

    It might work give a try.



    sudo rm /var/lib/apt/lists/lock
    sudo rm /var/cache/apt/archives/lock
    sudo rm /var/lib/dpkg/lock


    I not at tried ubuntu 19.04 versions so i'm not sure but the above commands may help you.

        apt upgrade doesn't solve it. I can't try your second suggestion because it tries to remove many of system packages (kde-runtime, kubuntu-desktop etc)

      sudo apt update && sudo apt autoremove


      and then



      sudo apt update && sudo apt upgrade

              It might work give a try.



              sudo rm /var/lib/apt/lists/lock
              sudo rm /var/cache/apt/archives/lock
              sudo rm /var/lib/dpkg/lock


              I not at tried ubuntu 19.04 versions so i'm not sure but the above commands may help you.
