Add br0 to Ubuntu desktop using nmcli

Add a bridge interface to Ubuntu desktop using nmcli

Had to do this for some advanced networking with KVM, and couldn't figure out how to do it using the Nework Manager gui. Did find an article later that showed how to do it with nmtui, but it's so much easier to record what you did when using the cli.

To see what everything looks like before starting:

Steps to enable GPG signing of git commits.

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

  1. Generate and add your key to GitHub
  2. $ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
  3. $ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
  4. $ git config --global alias.logs "log --show-signature" (now available as $ git logs)
  5. $ git config --global alias.cis "commit -S" (optional if global signing is false)
  6. $ echo "Some content" >> example.txt
  7. $ git add example.txt
  8. $ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)
