This is not an issue with ubuntu-release-upgrader, the software that conducts release upgrades, rather with the system after the upgrade.

After a while I put the system to suspended state. On awakening the system USB tethering does not work. After restarting the system it seems to work just fine and the process is repeated when I put the system to suspend again. Thanks.
