LinuxCNC Uspace

nice work
but isent there the stretch only to be practicle as ubuntu dosent suport preamt realtime anymore

If you build your own kernel (as Johns instructions show),
Any Debian based distribution including ubuntu should work

I'm running LinuxCNC uspace + Preempt-RT on Ubuntu18.04:

peter@dc7800:~/Desktop$ cat /etc/issue
Ubuntu 18.04.1 LTS \n \l
peter@dc7800:~/Desktop$ uname -a
Linux dc7800 4.19.10-rt8 #1 SMP PREEMPT RT Wed Jan 2 10:23:30 PST 2019 x86_64 x86_64 x86_64 GNU/Linux

John Thornton, Hello,
I have a problem upgrading from Debian 8 to Debian 9 ( Jessie to Stretch i think they are named ).

I followed these notes
gnipsel.com/linuxcnc/uspace/debian9-emc.html
I had no errors or warnings until
near the end I got this message
(while installing linuxcnc-uspace)

tomp@jessie:~$ sudo apt-get install linuxcnc-uspace

i already have libboost-python 1.55 and no 1.6 listed by synaptic
I already have libstdc++ 4.9.2.10+deb8u2 ,
( i have no idea what is meant by "is to be installed" , its already there )

some info about my system:

any hints?

Where John mentions stretch in the instructions you will have to replace it with jessie.

eg:
will be

Thanks for the answer
but
the effort is to upgrade from jessie ( what i got )
to stretch ( what i want to upgrade to ).

methinks keeping the repos as they were already would have no effect

are you sure about editing all 3 instances of "stretch" to "jessie" ?

Maybe I dont understand, willing to try but i got a munged system already.

Please comnsider my hesitation and tell me what you think.
Thanks
TomP

is there TCP M128 on the new ISO already provided

If you system is "munged", copy what you want from your home directory and do a fresh install with stretch.

A whole lot easier than trying to recover.

Just pick one of the three linuxcnc repos, don't add all three.
