How to migrate from Ubuntu 19.04 to 20.10? [duplicate]

  • 772

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

  1. 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.
