Thanks for the help @sdetweil and @CyruS1337. The latest suggestion gave me the same "Updating … " response.

I just renamed my MagicMirror folder and did a clean install. Everything is working great again. THANKS!

git remote -v

RESPONSE:
origin https://github.com/MichMich/MagicMirror.git (fetch)
origin https://github.com/MichMich/MagicMirror.git (push)

@sdetweil : Thanks. I gave that a try.

git pull

Updating de57daa…b508a62

npm install

[installs MagicMirror 2.6.0]

Sorry if this is an obvious question. I tried to update to 2.7.0.

From the MagicMirror folder, I type git pull && npm install

But the only response I see is “Updating de57daa…b508a62”. The I get the prompt back in a couple seconds.
