How to upgrade a package in a 3rd party repo via slackpkg

Hi,
Noob question here.
I installed slackpkg+. I enabled the alienbob repo. I currently have Python 3.7.2 installed on Slackware64 14.2. I used
Code:slackpkg search pythonand this is part of the results list:
Quote:

upgrade alienbob python3-3.7.2-x86_64-1_SBo --> python3-3.9.5-x86_64-1alien

I want to upgrade to newer version. I have tried:

Code:slackpkg upgrade alienbob:python3
slackpkg upgrade alienbob:python3*
slackpkg install alienbob:python3
slackpkg upgrade alienbob:python3*
slackpkg upgrade python3
slackpkg upgrade python3*None of those work. How do I make this upgrade?
