Hi,
I have some Linux mint 19 computers running LinuxCNC (axis) with some custom gladevcp tabs.
I would like to upgrade them  to newest master 2.9 (python 3), but I cant seem to get gladedvcp hal widgets working.

I managed to get it working on a fresh Linux Mint 20 computer, but i would love to not have to do a complete reinstall of my existing machine computers.

I read here: linuxcnc.org/docs/devel/html/gui/gladevcp.html

To view or modify Glade UI files, you need glade 3.38.2 or later installed - it is not needed just to run a GladeVCP panel. If the glade command is missing, install it with the command:

$ sudo apt install glade
Glade contains an internal Python interpreter, and only python3 is supported.
This is true for Debian Bullseye, Ubuntu 21 and Mint 21 or later.
Older versions will not work, you will get a python error.

And I cant seem to install glade 3.38.2 on mint 19, due to missing dependencies.
But one thing is editing, another is just running the widgets?

Is there another solution than a complete OS reinstall?

Mint is behind on versions of Python 3 and the kernel compared with Debian, It may have been resolved but I got bitten about 12 months ago and now use Debian Bullseye for everything. Good Luck!

I found this very disappointing

Where did "Mint 21" come from in the above post?
Mint is still at 20.3 till ... who knows...
And BTW, even on Mint 20.3 most of it will not work as it is stuck at Python 3.6.9 or similar while most of LinuxCNC stuff on Master requires 3.9.
I did manage to run Master on Mint 20.3, it was not pretty and it left a lot of broken hearts hmmm packages. :)

@Hansu,
Yup, thank you.
I wonder why?

Probably a typo. This line was added 7 month ago.
And I am not sure if it should say that Glade 3.38 is required. For me it works well with Glade 3.22.

check that Linuxcnc is installing the glade 3 widgets in the right file location.

They were not installed in the right location for me as I detailed here,

forum.linuxcnc.org/48-gladevcp/45387-mas...idgets-tools-loading

the "fix" was just to copy the contents of the Glade3 folder to the Glade folder ..... worked fine for me.

This was on Debian Bullseye, and I installed linuxcnc from locally compiled debs from locally cloned github repository.

@robert Did that also affect the execution of the widgets (with gladevcp) or only the availability of the widgets in the Glade designer?

Only the availability of the widgets in the Glade Designer, everything else worked fine.
