Ubuntu 20.04 LTS
 
Are there any [I]Ubuntu[/I] users here who have upgraded to 20.04 LTS? My [I]Ubuntu[/I] rig present an option to do the upgrade. I declined. I prefer to wait a while just in case there are any bugs found. 19.10 is running quite well for me.

Haven't upgraded but have tried the beta on a new system a few weeks before it became the final release, didn't encounter any problems. If there's no major reason to upgrade I'd wait until 18.04 users start getting the option to upgrade as that normally signals that the major bugs have been ironed out (which appears to be July/August, [url]https://linuxconfig.org/how-to-upgrade-ubuntu-to-20-04-lts-focal-fossa#h3-1-1-upgrading-from-ubuntu-18-04-lts[/url] ).



When you do upgrade you might want to remove snaps, they've become even more pervasive. If they keep pushing snaps I'm going to end up ditching Ubuntu for Debian Bullseye when it gets released.

I tried it, but gpuowl will not work. Reverted to 19.04.

I have a few machines on 20.04 (dual booted with Windows, or within a VM). No issues here.

Snaps. If I open the GUI file manager, I see a folder called "snap." It had the gnome calculator in it which I had added to my favorites on the left side.

I have an open terminal window running [I]LLR[/I] (Riesel). If I minimize it, there is all this open space on the screen. "Trash" in the far upper-left corner below another folder using my first name. It has the same content as the GUI when it is first opened. More folders are all I can place in this large space, it appears.

Sorry! I think I will stay with 19.10 quite a bit longer. There have been two minor updates since I reinstalled it. [I]mprime[/I] runs well on it as does [I]LLR[/I]. Just a scant few processes is all I want on it.

No serious issues yet post upgrade 19.10 to 20.4.
Only two issues have become apparent. The first is that Perl went from 5.28.1 to 5.30.0 and for unexplained reasons a bunch of CPAN-hosted Astro:: modules had to be reinstalled. The Ubuntu versions went swimmingly.

The other is that PostgreSQL jumped a major version. That is always a real PITA. The Ubuntu-provided database upgrade software doesn't handle pgSPhere correctly, despite the latter shipped with Ubuntu. do-release-upgrade flushes a library needed by the old binary before attempting to use it to update the cluster. I do, of course, have extensive backups and it was easy, though tiresome, to replace the file.

The house server is still on 18.04.03 LTS because do-release-upgrade is waiting for 20.04.01 LTS. I concur with that assessment.

Once we get a machine working for its assigned task we never upgrade anything on it after that. It's working, why risk breaking it? When a minion upgrades something on a working system I fire them immediately. If it ain't broke, don't fix it.

So I wonder what is 20.04 giving you that the older OS doesn't provide? If you had a working system then why risk breaking it?

[U]Agreed[/U]! I am running 19.10 on an eight-year-old HP workstation. It originally had Windows 7 Pro, according to the sticker on top. 32-bit probably. It had a wiped hard drive when I got it. It seemed sluggish with the 64-bit version of Windows 7 Pro. I added another drive and put [I]Ubuntu[/I] on it, and disconnected the Windows drive.

Note that Ubuntu 19.10 is only supported until July, as with all non-LTS releases (for 9 months). If you want a stable system that you don't want to update every 6 months, use an LTS release. I myself will upgrade both of my computers to 20.04 by the end of this month.

A machine is, by and large, not an isolate. It is a member of a mutually communicating and evolving ecosystem. The study of ecosystems has shown that mutation and/or adaptation is very often (not always) beneficial.

Case in point: a novel infectious agent makes its appearance in a population. Examples might be Wannacry and SARS-CoV-2. Members of the population which can change their response through mutation or innoculation tend to survive in rather better shape than those which can not.

Likewise if a novel supply of consumables becomes generally available it is useful to be able to adapt to the changed circumstances. Lactose tolerance and TCP/IP networking are examples of adaptations to newly available input.

Then it needs some change.

So my questions still stand unanswered: So I wonder what is 20.04 giving you that the older OS doesn't provide? If you had a working system then why risk breaking it?
