hub 2.7.0 installed on WSL does not authenticate with git-credential-manager

[mloskot]

Command attempted:

cd ~/boost/libs/gil
git switch develop
git pull origin develop
hub pr list

What happened:

$ hub pr list
github.com username:

I'm using git on Ubuntu on WSL and it is configured to use the git-credential-manager.exe

$ git config --get credential.helper
/mnt/c/Program\ Files/Git/mingw64/libexec/git-core/git-credential-manager.exe

and all Git commands, including push, work fine.

Apparently, hub does not use the credentials cached by the Git credential manager.

More info:

I'm using Ubuntu 20.04 on WSL on Windows 10.
Git and Hub installed from the Ubuntu packages.

$ hub version
git version 2.30.0
hub version 2.7.0

I do realise this is an ancient version of hub, but apparently that is what Ubuntu users are supposed to install as per #2697

It's the ancient hub version issue, see #2697 (comment)
