Update from 7.1 to 7.3: Now site says "Please run: bin/grav install"

(I don't think a grav update has ever broken anything for me before.) The site has run well for years on grav. But not sure how to proceed. Exactly where do I run this command? Hosted on dreamhost.

After SSHing in and making some adjustments to php 7.4 I was able to run bin/grav install. The result was:

ERROR Missing .dependencies file in user/ folder
HINT Are you trying to install Grav? Grav is already installed. You need to run this command only if you download a skeleton from GitHub directly.

It seems to be back to 7.1 and I am hesitant to try for 7.3 again. Should that work now?
