i have exactly the same issue , i tested with password, fine grained personal access token and personal access token classis, and nothing works for a private repo.
i then activated the github trial version of enterprise cloud , and make the repository internal, and create a fake github accoun and invited to my enterprise and tested again with the 3 methods (PW and 2 tokens) and it is not working, receiving the same error with status code : 401
can anyone guide me what i am doing wrong?
What and why it does not work:
The window for the extension management is kind of broken as Github does not accept username+password combinations anymore.
It should be redesigned both on the backend and frontend to take only tokens.
What works:
using the pyrevit cli (that comes installed with pyRevit), you can specify the token with the --token key
to install
pyrevit extend ui yourExtensionName https:\\github.com/user/repo.git --dest="C:/folder" --token=35684ger6384er63t5er635herzsh
to update
pyrevit extensions update yourExtensionName --token=35684ger6384er63t5er635herzsh
while using the cli, if you don’t know what to do with it you can always use: pyrevit **keyword** -h -h will bring the help for the keyword you want to use
when i try as you said above, i got this error, how i can solve this?
(knowing that i renamed my branch to “master” as indicated in the above replies)

try any of the wip installers in the past week or so here:

note: you will need a github account to grab the installer
i reinstalled the latest version 4.8.15 instead of 4.8.14 and now it finally works through the CLI 
Thank you so much for your replies.
But my main goal is to have an easier solution for the users who are not familiar with these commands, which is just replacing the extensions.json file which i will give them that include my repo link inside,
then all they need to do is to go in pyRevit Extension Manager tool inside Revit, and choose the repo and enter username and token, but unfortunately this not working, i get this error do you have any idea?
sorry for asking a lot of questions.
ERROR [Extensions] Error installing package. | remote authentication required but no callback set
Traceback: File "C:\Users\XXX\AppData\Roaming\pyRevit-Master\extensions\pyRevitCore.extension\pyRevit.tab\pyRevit.panel\Extensions.smartbutton\script.py", line 405, in install_ext_pkg extpkgs.install(self.selected_pkg.ext_pkg,
The idea that the token used in the CLI command is working well, but when the same token is used in the pyRevit Extension Manager tool inside Revit, it is not working for authentication issue.
i do not know if it is a token issue or something else maybe.
I will lock this topic @aymansaleh
