Review of Resolute Raccoon Kubuntu 26.04 LTS

[NoWorries]

I was able to download Kubuntu 26.04 LTS iso from the site:
https://cdimage.ubuntu.com/kubuntu/d...ive/current/:D

To my surprise when I created an installation disk, I was able to install it on my "Sacrificial Laptop" which is an ASUS F3Jr that I bought in December 2012. I am doing this post from my Resolute Raccoon site.

I have now installed all my favoutite applications and the Informaiton Centre is as ahown below.


While this is early days for this system, there are a few "gremlins" to deal with. I am sure that many of these will be solved in the coming weeks.

I must say that the greatest problem that I have is that I cannot view, copy or install my hidden files. My Calendar Kontact is now blank. I suspect that the hidden file problem is the reason for a great many of my problems as other applications have hidden files for their function.

As 26.04 is in the early development stage and the developers are making sure that this is a great LTS, I look forward to a great developmemt period where bugs and new feaatures are added.

Updates are still coming and the Info Center KDE Framworks has change from 6.19 to 6.20 in the past 5 days. Also hidden files are are now starting to become available, but my calender Kontact is still blank. It is great to experience the progress made by the developers in this short time.

[NoWorries]

My Calendar Kontact is still blank, and when I start it I get the following Konsole response.

$ kontact
MESA-INTEL: warning: Ivy Bridge Vulkan support is incomplete

​

I am not sure if I have not installed kontact correctly, but if anyone has Kontact working for them and can make sense of the above output, I would like to know.

At least updates are still coming and I live in hope that these will fix Kontact.

[NoWorries]

I am pleased to report that my calendar Kontact is now working with the exception of my Journal. I unfortunately failed to report that progress when it started to work.

All my laptops are now upgraded to Kubuntu 26.04 LTS and they are all working. The updates are still coming at a great pace and all my systems have not missed a beat.

I must say that the developers are doing a great job with this system and are to be congratulated. I wish them a very happy Christmas and I hope they have a well earned break.

It is now 4 Months to go before the release of Resolute Raccoon 26.04 LTS. This 4 month anniversary is just 2 days before Christmas and I wish you all a very Happy Christms and a joyful time celebrating with your family and friends.

I still have Resolute Raccoon installed on all my Laptops together with my favourite applications. So I have listed the current progress since the first release of 26.04 below.

	Ist Release of Kubuntu 26.04 LTS	4 Months to Kubuntu 26.04 LTS
KDE Plasma Version	6.5.2	6.5.4
KDE Frameworks Version	6.19.0	6.21
QT Version	6.9.2	6.9.2
Application Version	4:25.08.1	4:25.12.0
Kernel Version	6.17.0-5-generic	6.18.0-8-generic

As you can see, all major versions have been advance except the QT Version. I am very impressed with what the developers have achieved and are to be congratulated on a job well done.

I certainly hope that others on this forum are successful with getting 26.04 installed and are enjoying its stability. I am not sure how many updates to this system will happen between now and the new year. I hope that those involved in develpment have a well earned break. I certainly look forward to the developments of this LTS in the New Year.

Many thanks for developing such a great system and Happy Christmas to all who contributed and best wishes to the forum members.

It is now 3 Months to go before the release of Resolute Raccoon 26.04 LTS.

The developers are certainly continuing to provide updates to this system and I continue to find it completely stable.

To show the progress over the last month, the table below gives the current 3 month and the previous month info centre status.

	4 Months to Kubuntu 26.04 LTS	3 Months to Kubuntu 26.04 LTS
KDE Plasma Version	6.5.4	6.5.5
KDE Frameworks Version	6.21	6.22.0
QT Version	6.9.2	6.9.2
Application Version	4:25.12.0	4:25.12.1
Kernel Version	6.18.0-8-generic	6.18.0-9-generic

As you can see, the major versions have been advanced. I am very impressed with what the developers have achieved and are to be congratulated on a job well done

I certainly hope that others on this forum are successful with getting 26.04 installed. I suspect that some of you weary with the frequent updates, so I hope you can enjoy the progress being made.

All the very best for the New Year and all that it holds for the Kubuntu forum, members and developers.

I wonder if we'll ever see Plasma 6.6 in the final release so far it's rock stable with everything I throw at it.

[claydoh]

I wonder if we'll ever see Plasma 6.6 in the final release

It is almost 100% guaranteed, really. I haven't asked if this is the plan, but long-time history points that way.

6.6.0 release date
and
Ubuntu UI Freeze
and if I am wrong and this freeze is not relevant,
Then the Feature Freeze is still in a nicely favorable window.

[skyfishgoo]

it's impressive that they were able to get to 6.5.anything for 26.04... the LTS folks are on top if it.

nice work.

by the time 26.10 rolls around we may see 6.6 available in backports if they don't get it into the initial release.

[NoWorries]

To give an overview of the dependence of KDE Plasma development and its dependence on Frameworks and Qt, I refer you to the site:

https://community.kde.org/Schedules/Plasma_6

where you will find the interdependence of Plasma and the other versions listed above. So I hope the Schedules help to explain what the future development process involves.

Any one testing the Daily Builds of this via KVM? (Using 25.04, I have a reason for this, don't think it matters here really, but maybe it does... )
8C/16T AMD with 32GB RAM and host is kernel Linux rec9140-2504 6.14.0-15-generic #15-Ubuntu SMP PREEMPT_DYNAMIC Sun Apr 6 15:05:05 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

If that matters any, don't think so... but hey... may as well..

I may be biting off more than I should in this with KVM ( normally begrudgingly use VBOX, which is why I am using 25.04 for one thing, this is the first go around with KVM) and an alpha build, but hey.. Its more fun that way right?

Any way I grabbed the build ISO from yesterday 2/1/26, and it will boot in KVM under "Try" if I click the Installer to run it, it starts to do the install and implodes on itself spectacularly as its looks like its doing the partitioning setup for the VDISK (25GB)

I really prefer to do this in a VM situation v. bare metal, as the box I have for bare metal is not all that great, and I really need to use it for some other "experiments" right now.

So any one doing this in KVM? Thanks!
