        The Ubuntu team is pleased to announce the release of Ubuntu 20.04.1 LTS (Long-Term Support) for its Desktop, Server, and Cloud products, as well as other flavours of Ubuntu with long-term support.

        As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-impact bugs, with a focus on maintaining stability and compatibility with Ubuntu 20.04 LTS.

        Kubuntu 20.04.1 LTS, Ubuntu Budgie 20.04.1 LTS, Ubuntu MATE 20.04.1 LTS, Lubuntu 20.04.1 LTS, Ubuntu Kylin 20.04.1 LTS, Ubuntu Studio 20.04.1 LTS, and Xubuntu 20.04.1 LTS are also now available. More details can be found in their individual release notes:

        https://wiki.ubuntu.com/FocalFossa/ReleaseNotes#Official_flavours

        Maintenance updates will be provided for 5 years for Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud, and Ubuntu Core. All the remaining flavours will be supported for 3 years. Additional security support is available with ESM (Extended Security Maintenance).

        thank you, Alex for the update. have you run the ZFS filesystem instead of ext(4) on Ubuntu? i’ve seen the option to format with ZFS for a while now but haven’t tried it.

          I don’t run Linux 🙂
          Just updating on new news.

          ZFS is all kinds of nice in the right situation.

          It’s also very complicated and the optimization is sort of exotic too, and the greatest benefits happen on servers with lots of separate physical storage devices directly attached and plenty of RAM available.

          On a system with a single storage device or just a simple pair of large/slow and small/fast, well in that case any benefits over… say, BtrFS, or straight Ext4 or XFS over LVM… are dependent on workload and specific hardware. (ZFS notably does very well as backend storage for virtualization, where BtrFS in turn is particularly weak.)

          But if you absolutely need performance on your server, doing the optimization calculations and building the correct kind of ZFS layout is often a good way to get it.

          ZFS is also an off-tree kernel module, so its compatibility with other such (GPU drivers, certain antivirus products, certain hardware RAID…) is never guaranteed. Well, the hardware RAID thing you usually shouldn’t want to do much with ZFS anyway.

            thank you for your kind reply, mn-. i’m building the ubuntuunity 20.04.1 in between typing this. i guess i’ll go with the ext4 if ZFS isn’t so exciting…

              ZFS has no value for “normal” users as it provides no benefit above a good backup and has very high RAM requirements. Buy a fast SSD and back it up regularly.

              In a File Server with lots of disks and ECC RAM is can be a very good, reliable file system.

              cheers, Paul

                Well actually… depends, but very much a niche thing.

                If you really want frequent snapshots and also happen to be doing one of the various things BtrFS does badly with, ZFS very much can be worth it even on a laptop. (Just have to be careful with swap/hibernate space.)

                15-minute snapshots kept a few hours becomes sort of nasty with XFS or Ext4.

                Snapshots are the one good thing about ZFS, but “normal” users don’t use them.

                cheers, Paul
