Public bug reported:
My laptop Lenovo IdeaPad S145 was working perfectly till a few days ago.
I use a wireless keyboard (Lenovo 100 Wireless Combo Keyboard) for
convinience. Since the past few days it's typing '<' automatically. I
tried to Update my ubuntu 18.04 to 20.04 but it failed.

Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
This was likely caused by:
* Unofficial software packages not provided by Ubuntu
Please use the tool 'ppa-purge' from the ppa-purge
package to remove software from a Launchpad PPA and
try the upgrade again.
If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If
you want to investigate this yourself the log files in
'/var/log/dist-upgrade' will contain details about the upgrade.
Specifically, look at 'main.log' and 'apt.log'.
