[Bug 1894623] [NEW] not able to upgrade linux neither i am able to install google chrome inspite of trying to install it multiple times

[Aayushi SIngh]

Public bug reported:

Tried upgrading my linux from version 16 to 18 to which it showed the
below error:

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.

i have also tried installing google chrome and honestly everything
seemed normal while installing and after i complete the installation
process i would see that google chrome still hasn't been installed. When
i tried opening the google chrome package again it showed 'install' bar
instead of 'remove' bar. I have tried installing google chrome through
terminal but to no avail it has helped.
