RTAI with 4.19.152 - Bugs Fixed. Testers Needed

Did you install rtai-modules also ?
To much stuff missing there.

Of course.

Use
sudo apt-get install gdebi
then use gdebi to install packages. DPKG does not check for all the dependencies causing some issues.
so :
sudo gdebi rtai-modules-4.19.152_5.2.3-linuxcnc_amd64.deb
edit
do the same for the kernel, reinstall it

I installed it without problems using gdebi, except when installing linuxcnc_2.8.1_amd64.deb I got the error:
This package is uninstallable
Conflicts with the installed package 'linuxcnc-uspace'
So, I removed linuxcnc using the synaptics package manage, and it installed after that.

I tried latency-histogram , and it usually worked. However occasionally I get a servo latency of -999.8 right at the start and the following error messages:

msg=can't use non-numeric floating-point value as operand of "*" (variance=-1014672226)
msg=can't use non-numeric floating-point value as operand of "*" (variance=-1558858668)

Finally I reinstall OS.
Everything goes ok, except one dependency: python-gtksourceview2.
I have to install it manually.
