I'm trying to migrate a Ubuntu 19.04 install to the last Ubuntu version. The problem is the migration tool refuses to update to the next version:

Can not upgrade 

An upgrade from 'disco' to 'focal' is not supported with this tool. 

How can I migrate instead of a fresh install where I would have to reconfigure everything?

Thanks in advance for your kind help

    The unfortunate part is that there isn't an upgrade path from 19.04 to 20.10. The path would have to go to 19.10 first, which is EOL as well and not upgradeable/installable. It would have to be a clean install to 20.10.

  • I remember having to do something similar once. I think there is a way to trick the upgrader into thinking you are on a different version, but things can get very unstable after that. You could also do a reinstall where you preserve the /home/ directory, so you only have to reinstall programs, not reconfigure anything. Oct 23, 2020 at 18:01
  • You can't skip release when upgrading. 19.04 went EOL in January. You should upgrade before your system reaches EOL. Its successor 19.10 also went EOL in July. Unfortunately, this probably means you've waited far too long to upgrade your current system, so your only path is likely to install a supported release from scratch. Don't ever let your OS go EOL because that means your support has lapsed. If you don't want to upgrade every 6 months, stick with a LTS release like 18.04 or 20.04 - they are supported for 3-5 years. wiki.ubuntu.com/Releases

    You should probably install 20.04 instead of 20.10 if you are not going to be prepared to upgrade again between April and June of 2021, and every 6 months after

You missed the boat, sorry.

There is no tested upgrade path from 19.04 to 20.04 nor to 20.10.

The upgrade window for 19.04 to 19.10 closed in July 2020.

The supported, recommended, safe, easy way is to create a new 20.04 or 20.10 install USB and clean-install.

The unsupported, untested, blaze-your-own-trail way is to manually change your sources, then run a dist-upgrade. However, we don't provide support for it: If you run into problems, we will merely recommend a clean-install.

  • 19.04 stopped receiving security patches in January 2020. That alone is reason enough to clean-reinstall.
