Lubuntu 18.04 will not be able to upgrade directly to Lubuntu 20.04 Focal Fossa

Focal Fossa will introduce important changes. For me, the highlight will be the complete and improved support for the ZFS as root, which, among other things, will allow us to save checkpoints / restoration as in Windows. There will also be internal improvements and some of them, although they will be positive, may be a problem. This is what Lubuntu has made known since Official Twitter account, where they explain that it will not be possible to upgrade directly from Lubunutu 18.04 to Lubuntu 20.04.

He has done it through the three tweets that you have after the cut. The most revealing is the third and last, where they tell us directly that the update from 18.04 to 20.04 will not be supported. This is due to there will be many technical changes, something that, remember, already happened in Plasma from KDE 4 to Plasma 5. Therefore, the Lubuntu team recommends that we get used to the idea and take the first steps right now.

There will be many technical changes from Lubuntu 18.04 to Lubuntu 20.04

As of today, the Lubuntu CI no longer builds packages for Lubuntu 18.04.

This means that 18.04 users can no longer use LXQt through our PPAs, and should upgrade to 19.10: https://t.co/1uhattVZ29

This does not affect current 18.04 installs, only users of the PPA.

Upgrades from 18.04 LTS to 20.04 LTS will NOT be supported. This is due to the major technical transition: it simply isn't possible for us to transition users safely without a reinstall.

(This was also the case in Kubuntu transitioning from KDE 4 to Plasma 5.)

If you have not upgraded to a newer installation of Lubuntu, you should do so as soon as possible, or when 20.04 LTS is available.

Upgrades from 18.04 LTS to 20.04 LTS will NOT be supported. This is because of the big technical transition - we just can't safely transition users without a reinstall.

Lubuntu 18.04 users should upgrade to Lubuntu 19.10, if they want to be able to upgrade from the operating system to Focal Fossa next April. What the editor of this article would recommend would be to keep this in mind and update to Eoan Ermine about March, a month before the launch of Focal Fossa and after 5 months in which the developers will have already fixed the most important bugs of 19.10. In any case, keep in mind that this time the jump from LTS version to LTS version will not be possible.
