A new upload with a 'fix' is on the way...

Not even 24 hours. Ya gotta love this!

[jglen490]

Yep! Looking forward to the end of April ...

Finally!

Qt4 has now been removed from the 20.04 archive.

Synaptic History

There was 168 packages to upgrade in Proposed for yesterday's build (18 today). A blue message was shown to stop some services while upgrading. Since at least a week, the installer scans the HD for NVDIA... We must press S twice to skip HD scan.

-History is empty in Synaptic
-Muon works normally
-Encrypted successfully message does not display correctly
-At boot, the message to remove media appears intermittently.
-Taskbar issues are gone
-Driver Manager requires root password now and scans normally

Dolphin does not read Tumbleweed bootable stick, same for Device Notifier on the taskbar. The rest is OK = fat32, Windows, Mint.

The remove media message interferes with the LVM passphrase, both are shown rapidly back to back. This is a one shot message that is not removed from the boot sequence. When not encrypted (ext4 or btrf), the message appears permanently at boot time since day one.

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

[acheron]

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

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.

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.

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".

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.

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=""

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.

Me too!
