Need more information

Thank you for taking the time to file a bug report.

"""

"""

Since there is not enough information in your report to begin triage or to
differentiate between a local configuration problem and a bug in Ubuntu, I
am marking this bug as "Incomplete". We would be grateful if you would:
provide a more complete description of the problem, explain why you
believe this is a bug in Ubuntu rather than a problem specific to your
system, and then change the bug status back to "New".

For local configuration issues, you can find assistance here:

Hi R J Nawara,
your issue has the same top level symptom (package can't be installed) but might have a totally different root cause. I'd want to encourage you to file a new bug and add as much debug log content as possible to be able to differentiate from other cases.
