I got Ubuntu's upgrade notification and I started upgrading my installation. For some reason I had to abort the upgrade and shut down the system which led to the corruption of entire installation. Hence, I was not able to boot the installation normally and here are the steps which I had followed to recover the system:
1. Pressing shift button when the system started led to see the boot menu and I had selected one of
the old recovery images.
2. sudo dpkg --configure -a
- installed the package maintainer's version.
3. Upgraded the system from updates gui.
4. There were lots of images so I had to purge the ones which were not required:
- sudo apt-get purge "linux-image-version_of_the_image_to_remove" (w/o quotes)
- sudo update-grub2
5. sudo reboot
- Pressed shift button to show the boot menu -> went to advanced options.
- The new image and its recovery were listed. This is because of purging the old images as above.
