Error installing QTPlasmaC latest

Hi,I installed a new system from a 2.8 live CD ISO. I then changed the repository to buildbot.linuxcnc.org master-rtpreempt.I used PNCConf to create a new QTPlasmaC config. When I tried to load I got this error.

I removed the requirement for qtwebkit today but it looks like the Buildbot hasn’t started that build yet. In the meantime you could try installing python3-pyqt5.qtwebkit.

I installed last night so I will be out of sync. Thanks I will try the webkit or just wait a day.

On that note, will the Synaptic Package manager pick up the latest release from Master?

Yes if your sources.list files include the Linuxcnc repository.

Rod do you mean the deb buildbot.linuxcnc.org? I have that in the list but not the deb linuxcnc.org

To work with master branch, I think you would be better off working with Bookworm and following this guide
linuxcnc.org/docs/2.9/html/getting-start...etting-linuxcnc.html
Under heading #9 the line that starts with echo change to

But if you must stick with buster which I have not used for a few years, you should be able to follow this
buildbot.linuxcnc.org/

THere have been so many changes with the OS, Master is based around Bookworm, so you are likely to hit issues with it on Buster. Just my opinion.

To my knowledge, despite your updates to the "Getting LinuxCNC" sections of the docs to point everyone to Bookworm, the project has not officially aligned to any particular distribution of Linux. Until we officially pick a Debian version to work to, I choose to do my programming/testing on Buster due to the Live ISO.
 

Yes its frustrating for sure. I was aked to update the getting linuxcnc docs for bookworm so I did with some input from others. I wrote it from the assumption it would be on Bookworm. To the best of my knowledge there are only 6 outstanding issues that are marked 2.9 must fix. There are no pending pull requests for 2.9 must fix. If past experience is a guide, one of the senior developers will have a dummy spit one weekend (hopefully soon) and the next thing you know, it will be deployed in a couple of days. I lost all interest in Buster during the transition from Python 2.7 to 3.x. That was just before Bullseye was released and here we are now with Bookworm released a couple of years afterwards.

It must be about 7 years since 2.8 was released by my memory. That means a couple of generations of hardware have been and gone. Its not really good enough to take that long between versions. How long since 2.9 was hived off pending a release? How many meetings around the world has there been since then where a release was discussed?

There are so many improvements to the Linux platform in general and Debian is now on the 6.1 kernel with full UEFI/Secure boot support (Buster is 4.19).There are many drivers in Bookworm that are not in Buster. I have one PC I started with on Mint 17.3 with a compiled RT kernel (which was the way before there was a stretch image) that has about 1/3 of the latency it had back then. This demonstrates the substantial performance  improvement made in the Linux kernel. 

 So if you want to run on old hardware, Buster might be fine but to use the more modern USFF industrial PC's, its highly likely you will have issues that you won't resolve on a Operating system 2 versions behind the current state.

I've just recently reimaged my Windows Work Desktop with Debian 12.1 and sometimes I am gobsmacked by the speed improvement over Windows doing simple tasks. Some people insist on using Ubuntu, Mx Linux, Mint and others that are based on Debian. Often, these kernels drag behind and desired features are not present. But Debian has. eg Ubuntu just got the preempt_rt kernel and they have the afront to make it a paid add on. I never see posts on the RT users group from the Ubuntu team. but now closed source Red Hat often make contributions, even offering to help me personally with RT network performance.

Anyway rant over. The benefits of Bookworm and a modern kernel for me far outweigh attempting to find old hardware to run Buster. It has been that way for about 3 years for me.
 

I seem to be doing a lot of upgrades from Mach3 to Linuxcnc lately and I have to use the most effective way to get the system installed. Using the live CD based on Buster is the best way for me. I have been using the master branch for some time now and this is the first issue that I encountered. As Phil said, the buildbot has not caught up yet.
Well it is the second day now and it still is not caught up yet.
