Ubuntu 20.04
Ubuntu 20.04 (aka Focal Fossa) is out, including arm64 and armhf builds for the Pi! There's been a lot of testing behind the scenes on this one, but there's still a few rough edges so do be sure to check the
release notes (especially if you have a
Pimoroni fan-shim!).
Probably the easiest way to get it is with the Pi Foundation's
new imaging tool, otherwise you can find it on our
Pi Downloads page. Do feel free to report any general experiences here, but if you have specific issues it's probably best to open a new thread or open a bug on
Launchpad.
Have fun!
Dave.

is that "renderer: networkd" needed now? it's not in the how to.
everything else is pretty much what i got.
i removed the "dhcp4: true" cause it just kept throwing errors in "sudo netplan --debug try"

@kerry_s, your wording is a bit unclear. Am I correct that your wifi
still won't work, even with "renderer: networkd" added,
and the removal of "dhcp4: true"?
Or will wifi work with "renderer:networkd",
but you need to set a static IP address? And if so, how does one set a static IP addess in that pernicious .yaml file?

hold on I'm waiting for it to boot, to try adding that part.
I'm gonna try a put it exactly like his example, be back in a bit.

as far as i remember the networkd fix was for the gui network manager. i haven't even connected to the internet once yet, so no gui installed.

Netplan supports both networkd and Network Manager as backends.

looks like a success, i wrote it in vi exactly how he posted the example.
now i just got to decide on what GUI install I'm going to do.
netplan is a piece of rubbish, on Ubuntu 20.04 (Focal Fossa)

Sorry, that doesn't work for me. Even when I try to run "sudo netplan --debug try" afterwards.
After a fresh imaging of a MicroSD card, there will be a tempting "network-config" file in the partition with the boot-related stuff (labelled "system-boot"). Either working from the wifi example provided in that file,
or putting that paragraph above into this "network-config" file before first boot doesn't work either. Yes, I substituted in my own password, and SSID.
Would you like to see the error message? Sorry, I can't provide it. Why? Because the RPi4 has no network connectivity.
People, use an ethernet cable, lest this issue drive you crazy.

yeap, i hear ya.
i had to put it in "50-cloud-init.yaml" to get wifi to work in ubuntu-desktop-minimal.
now i'm just kludging my way around, haven't used ubuntu in ages & there have been a few changes.

Here's further why I think netplan is a piece of rubbish. It fools you into believing it has automagical powers to make everything gracefully adapt, even when common problems arise, but then it doesn't gracefully handle problems like I'm having. It gives no helpful error messages. It throws up obscure python errors (netplan itself threw up python exceptions that weren't caught). To me, that's sloppy coding, as the error messages are very long and obscure.
For me to ever trust and like netplan, I would like to see all possible exceptions get gracefully caught (knowing ahead of time all the possible ways networking can somehow fail, at many levels and layers), then yield a brief, helpful, non-vague error message, suggesting what to change, or check, if possible and obvious.
Until then, it does more harm than good. It creates more problems than it solves.

it's just not made for our kind of use.
if you need a server and have ethernet, it's good to go.
to me it's just slow and the snap packages thing, i think that above all was the reason i left ubuntu.
i really wish pop!_os had a raspberry pi version, i would be all over that.

Personally, I found ubuntu to be slow to boot, when I install lubuntu, it installed nearly every ubuntu desktop to ever exist.
It also wouldn't recognise my HDMI touch screen, so I couldn't pixel double.
Wait till ubuntu MATE release an official image for Pi4. They do a good job generally.
I'm stuck with manjaro with very little hardware acceleration.
I'll wait for ubuntu MATE

Spent nearly entire day trying to get display via vnc or rdp to work (I am using a headless install and don't have a hdmi monitor). Tried installing lubuntu , xubuntu, kubuntu. But it still fails. Looking a bit deeper into it, I found that there is an issue with XORG driver.
Here is the XORG log file. It would be great if anyone can help me. Besides, the wifi works fine, though I did have to connect it via Ethernet initially.

Hi all,
I have installed and updated Focal Fossa (20.04 LTE) on my RPI 4 (4mb ram) using the Ubuntu Desktop. After some "hacking/Google" all works fine e.g. WiFi, LAN, Bluetooth, Sound etc. The only thing I have not yet managed to fix is overclocking. When I add the parameters to "/boot/firmware/config.txt" and reboot, the system will not start at all. Only after removing the parameters it will boot as normal. Has anyone experienced the same or have a solution? I am using exactly the same parameters I used in 18.04 and/or 19.10 where it all worked well.

just curious in your about it it using llvmpipe for video?
also are you 32 or 64 bit? i was 32bit in my testing.

Hi,
Yes I did add it to boot/firmware/usercfg.txt but still a problem when booting. Not sure about "llvmpipe" , I have not installed any additional video drivers. Using Kodi or VLC for videos, Clementine for music. I am using the 64-bit version since I have 4Gb ram and it is supposed to be faster.

hmm, i'm just looking at my usercfg.txt & i guess i didn't even try overclocking.
if i remember right, playing video would spike my cpu's above 50% & drive temps around 60, so i didn't want to chance overclocking.
if you give me the overclock your using, i can see if it boots on mine.

This seems a bit too good to be true but...
Would this improve the graphical performance of the desktop?
I might consider ubuntu for the Pi...
