Final Focal on Kubuntu 20.04

[Snowhog]

Nope. Muon was removed. Here is the 'trail':

The following packages have unmet dependencies:
muon : Depends: apt-xapian-index but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

The following packages have unmet dependencies:
apt-xapian-index : Depends: python3-apt (>= 0.7.93.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

python3-apt is already the newest version (1.9.10).
python3-apt set to manually installed.

So, it looks (to me) that the issue is a problem with packaging version information with python3-apt.

[Snowhog]

Performing an update and full-upgrade on my 20.04 system 'as I type'. I noticed that:

Removing muon (4:5.8.0-1ubuntu5) ...
Removing apt-xapian-index (0.49ubuntu3) ...
Removing index /var/lib/apt-xapian-index...

I'll verify or disprove that Muon Package Manager isn't available after the full-upgrade completes.

[Teunis]

Curious, here I don't have this problem.

Moun's history tab tells me it was last update yesterday the 23th.
apt-xapian-index was part of the original install on the 6th and there has not been an update since.

Another small problem that arose this morning is that Muon is no longer working. I found that it was no longer installed on my system and when I tried to install it, I got the error message

sudo apt install muon
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
muon : Depends: apt-xapian-index but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

This problem impacts all systems, so will have to wait for a fix.

[Teunis]

Indeed, so far a very good distro.

One small problem is it's no longer possible to toggle the touchpad on/off.

[GreyGeek]

Me too!

It is now the final month to the release of Focal.

I am continuing to find this to be a very stable distribution.

Dolphin continues to not show "Removable Devices" when launched on my system. I have to right mouse click in the left panel "Places" and select "Show Hidden Places" each time I want Dolphin to remove an attached device.

With my Pre-release updates selected, I get the current status of Info Centre versions shown in this table.

	2 Months to go	1 Month to go
KDE Plasma Version	5.18.1	5.18.3
KDE Frameworks Version	5.67.0	5.67.0
QT Version	5.12.5	5.12.5
Kernel Version	5.4.0-15-generic	5.4.0-18-generic

I am very pleased with the steady advancement of the Focal LTS. It will be interesting to see if the Kernel Version 5.6.0, used by Radcliff above, becomes available in a Canonical ppa.

[Radcliff]

Kernel PPA

While I have no problems with the first 3 Versions listed above, I find it problematic that you have Kernel Version: 5.6.0. I have not found any canonical ppa with Kernel 5.6.0. So I assume that you have built and install it in your version of Kubuntu 20.04.

So while Kernel 5.6.0 has many very desirable improvements, I would be very wary of any instability in your installation with this Kernel.

There is one available every Sunday night on the East Coast. Kernel PPA:

https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

You need to download 4 packages:

linux-headers-5.6.0-050600rc5_5.6.0-050600rc5.202003082130_all.deb
linux-headers-5.6.0-050600rc5-generic_5.6.0-050600rc5.202003082130_amd64.deb
linux-image-unsigned-5.6.0-050600rc5-generic_5.6.0-050600rc5.202003082130_amd64.deb
linux-modules-5.6.0-050600rc5-generic_5.6.0-050600rc5.202003082130_amd64.deb

Complite them that way, just make sure there are no other .deb files in the Downloads folder:

cd //home/yourusername/Downloads

sudo dpkg -i *.deb

They have nothing to do with problems that I've been reporting, simply because they're also in stock Kernel. This week, they are not available for the given reason 5.6-rc6.

The bug with messages is gone for a week, same for the Tumbleweed flash drive. Only Synaptic issue remains: It records internal stuff, but not incoming updates.

Lastly, mainline Kernel is not unstable here, corrections via telemetry are applied on next Sunday. We Just see it as a supplementary source of excitement.

https://lkml.org/

Edit:

You must boot in the Grub menu when enabling the mainline Kernel channel. Grub must be set that way when not dual boot:

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=false
GRUB_TIMEOUT=7
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

I keep getting a message that this thread has been moved. I am not sure where it is going but I can still post problems that I am having. I just hope that a solution can be found

On both of my systems with 20.04, I keep getting the error with initramfs-tools. I realize that this has been fixed, but I still get this error message after each update.

I hope a solution can be found to this problem, as it is annoying to see it still happening after the "fix".

Same here, no problems BUT I did a fresh install on the 8th. because of multiple problems including the initramfs one.
Presently all is working very well, including some proprietary software like Nvidia, Vuescan, a Xerox printer and Softmaker Office.

[Snowhog]

It must not affect everybody. I just did a full update-upgrade and I encountered no errors.

I checked this morning, and I was already on a version of libc6 'after' that that was affecting the affected.

[acheron]

It is probably only people who did an upgrade last Sunday, and got a bad package before it was pulled.
