Update server via command line

My web interface is broken. I was thinking of running an update. Is there a way to update via command line?

ssh user@yourserver

if you didn’t user the ppa the first time :
sudo add-apt-repository ppa:uroni/urbackup

sudo apt-get update
sudo apt-get install urbackup-server
systemctl restart urbackup-server
