setting up git for access token on Ubuntu 20.04

gistfile1.txt

# Install gpg helper tools
sudo apt-get install gnupg-agent pinentry-curses
# Fix permission on the included git-credential-netrc
sudo chmod a+x /usr/share/doc/git/contrib/credential/netrc/git-credential-netrc

# create a GitHub access token for this
# Go to Settings -> Developer Settings -> Personal access tokens -> Generate new token
# We will save the token in an encrypted .netrc file below

# create a gpg key (if you do not have one already on the machine)
gpg --gen-key

# create a .netrc file
machine github.com
login yourgithubid
password your-github-access-token
protocol https

# encrypt the .netrc file for the key created above and remove the original
gpg -e -r your.email@address ~/.netrc
rm ~/.netrc

# Tell git to use the git-credential-netrc that came with git
git config --global credential.helper /usr/share/doc/git/contrib/credential/netrc/git-credential-netrc

# apply the fix below if you see errors like:
#   gpg: public key decryption failed: Inappropriate ioctl for device
# Source: https://d.sb/2016/11/gpg-inappropriate-ioctl-for-device-errors

# put this into ~/.gnupg/gpg.conf
use-agent 
pinentry-mode loopback

# put this into ~/.gnupg/gpg-agent.conf
allow-loopback-pinentry
