Requirements

  • Ubuntu 21.04 Hirsute Hippo installed.
  • Internet access that is fast and reliable (unlimited one is the best).
  • Free time, as it could take more than one hour.
  • Enough free disk space, please give at least 5GB free.

(Ubuntu 21.04 Hirsute Hippo before upgrading)

Step 1. Reload

Firstly, do the Reload command line below. 

$ sudo apt-get update

This command introduces your Ubuntu Hirsute to its latest updates from its repository. This does not install nor upgrade any new program.

(The update command)

Step 2. Upgrade Current Version to Its Latest

Second step is to upgrade 21.04 to its fullest. This does not upgrade your system to Impish Indri version yet.

1. Do the Upgrade command line.

This command takes about 400MB on a fresh Hirsute Hippo and should be bigger on a used system. This may takes time up to 1 hour.

$ sudo apt-get upgrade --yes 
(The upgrade command)

2. Do the Dist-Upgrade command line.

Once upgrade succeeded, do the dist-upgrade below. This command takes about 200MB on a fresh Hirsute and should be bigger too on a used system. 

$ sudo apt-get dist-upgrade --yes

(The dist-upgrade command)

Step 3. Restart

Reboot your Ubuntu computer and continue the next step.


Step 4. Upgrade System to New Version

After rebooting, now you do several final steps to finish the upgrade.

1. Do the Do Release Upgrade[1] command line.

2. Accept with yes (first time).

3. Accept with yes (second time).

4. Accept with yes (third time).

5. Accept with yes (last time).

6. Restart. 


Command line:

$ sudo do-release-upgrade 

This process takes up biggest download as well as disk space on a fresh system, that is, a 1GB, and should be more on a used system. As a consequence, this may takes up longest time too.


The Result

Once restarted, Ubuntu system should now be 21.10 Impish Indri. Congratulations!
