Ubuntu (Focal Fossa) OS Upgrade V18.04.6 LTS – V20.04.5 LTS

Posted by Sriram Sanka on November 1, 2022


Ubuntu is a Linux distribution based on Debian and composed mostly of free and open-source software. Ubuntu is officially released in three editions: Desktop, Server, and Core for Internet of things devices and robots. All the editions can run on the computer alone, or in a virtual machine.

You can download OS VM Images from either https://www.linuxvmimages.com/ Or https://www.osboxes.org/virtualbox-images/

Ubuntu Can be Upgraded to the Latest using 3 simple steps.

  1. Update – get all the Package Updates.
  2. Upgrade – Package Upgrades to the Latest.
  3. do-release-upgrade – do-release-upgrade handles checking for a new release, updating sources. list , and a range of other tasks, and is the officially recommended upgrade path for server upgrades which must be performed over a remote connection.

You can see if the Latest is available when you login

Continue running under SSH?

This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because in case of failure it
is harder to recover.

If you continue, an additional ssh daemon will be started at port
'1022'.
Do you want to continue?

Continue [yN] y

Starting additional sshd

To make recovery in case of failure easier, an additional sshd will
be started on port '1022'. If anything goes wrong with the running
ssh you can still connect to the additional one.
If you run a firewall, you may need to temporarily open this port. As
this is potentially dangerous it's not done automatically. You can
open the port with e.g.:
'iptables -I INPUT -p tcp --dport 1022 -j ACCEPT'
