@chinmayrajyaguru There’s a few things we can do in an effort to resolve this. First, I’d clean up the lists for apt-* by running: sudo rm -rvf /var/lib/apt/lists/* The above command removes all files and directories located in /var/lib/apt/lists/, which will then be repopulated at the end. Now we’ll configure the cache limit by running: echo "APT::Cache-Limit "100000000";" >> /etc/apt/apt.conf.d/70debconf The above command simply adds APT::Cache-Limit "100000000"; to the end of the /etc/apt/apt.conf.d/70debconf file. At this point, run: sudo apt-get update And see if you’re able to successfully complete the action. If not, please run: sudo rm -rvf /var/lib/apt/lists/* \ && sudo mv /var/lib/dpkg/status /var/lib/dpkg/status-bad \ && sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status \ && sudo apt-get update If successful, you should be good to go. You may also want to clean up any packages that are not currently in use: sudo apt-get autoclean \ && sudo apt-get autoremove -y \ && sudo apt-get update The above command will clean up information / cache used by apt-*, remove packages that are not currently in use by existing software (perfectly safe as this command only selects software that isn’t actually being used by current packages) and then runs the update command once more. Lastly, I’d run a quick upgrade to make sure that all current packages are up to date: sudo apt-get upgrade -y

It looks like you’re out of memory. I would check if there aren’t processes on the same VM using a lot of it.
