[galaxy-dev] Problem upgrading

Hello,

I'm currently running Galaxy 16.01, and I'd like to upgrade to 16.04. However, when I attempt to do so, I get an error, and git log shows I'm still on 16.01.

$ sudo git checkout master && pull --ff-only origin master M tool-data/all_fasta.loc.sample Already on 'master' -bash: pull: command not found

I also tried updating to the exact version:

sudo git checkout v16.04 error: pathspec 'v16.04' did not match any file(s) known to git.

For the record, I'm using Git 1.7.1. I took my commands directory from the announcement page at https://docs.galaxyproject.org/en/master/releases/16.04_announce.html

Any suggestions for ways to get the 16.04 code are greatly appreciated!

Best,
