How to update your standalone ESXi 5.5 host

Enable SSH access on your host, log in to it (e.g. using putty) and run the following commands:

1 # open firewall for outgoing http requests:
2 esxcli network firewall ruleset set -e true -r httpClient
3 # Install the ESXi 5.5 U1 Imageprofile from the VMware Online depot
4 esxcli software profile update -d -p ESXi-5.5.0-20140302001-standard
5 # Reboot your host
6 reboot

This will also work if you are still on ESXi 5.0 or 5.1.
