Question

How do I upgrade Ubuntu from 16

following: https://www.digitalocean.com/community/tutorials/how-to-upgrade-to-ubuntu-20-04-focal-fossa

When I run sudo do-release-upgrade, i get this error:

Please install all available updates for your release before upgrading.

I’ve tried running tons of different commands and nothing gets me past this.

The article does not address it, nor are the other comments with this issue answered.

Hello there,

As with almost any upgrade between major releases of an operating system, this process carries an inherent risk of failure, data loss, or broken software configuration. Comprehensive backups and extensive testing are strongly advised.

To avoid these problems, we recommend migrating to a fresh Ubuntu 22.04 server rather than upgrading in-place. You may still need to review differences in software configuration when upgrading, but the core system will likely have greater stability. You can follow our series on how to migrate to a new Linux server to learn how to migrate between servers.

Hi @skeddtemp,

You need to execute the following commands prior to running the do-release-upgrade one:

  1. apt update
  2. apt upgrade
  3. do-release-upgrade

That should be it! Additionally, if there are still issues, can you please provide us with the output of both apt update and apt upgrade?
