To retrieve your server version, in your server's terminal, run:
cat $(npm root -g)/lamassu-server/package.json | grep "lamassu-server@"
You'll see an output similar to that below:
root@lamassu-cryptomat:~# cat $(npm root -g)/lamassu-server/package.json | grep "lamassu-server@"
In this case, your present version is 7.4.7.
