Folks,

I followed this tutorial and it worked fine with mint 19:
gnipsel.com/linuxcnc/uspace/linuxmint19-emc.html

when i installed that, I used build 2.7, it worked fine. I get this from -v
LINUXCNC - 2.7.15

Then when I wanted to install the master, 2.9pre, and I encountered a problem.

There were residual .deb files in my home area, so I removed all those. Then I ran all commands on the mint 19 install page up to:

$ debuild -uc -us

and installed the .deb files, now I'm getting this from
$ linuxcnc -v
Verbose mode on
RUN_IN_PLACE=no
LINUXCNC_DIR=
LINUXCNC_BIN_DIR=/usr/bin
LINUXCNC_TCL_DIR=/usr/lib/tcltk/linuxcnc
LINUXCNC_SCRIPT_DIR=
LINUXCNC_RTLIB_DIR=/usr/lib/linuxcnc/modules
LINUXCNC_CONFIG_DIR=
LINUXCNC_LANG_DIR=/usr/lib/tcltk/linuxcnc/msgs
INIVAR=inivar
HALCMD=halcmd
LINUXCNC_EMCSH=/usr/bin/wish8.6
LINUXCNC - 2.9.0~pre0

so that looked like good news but when I run linuxcnc and try to start any of the sims I get:
LINUXCNC - 2.9.0~pre0
Machine configuration directory is '/home/owhite/linuxcnc/configs/sim.axis'
Machine configuration file is 'axis.ini'
Traceback (most recent call last):
  File "/usr/bin/update_ini", line 11, in <module>
    from tkinter import *
ImportError: No module named tkinter
update script failed in an unexpected way.
LinuxCNC terminated with an error.  You can find more information in the log:
    /home/owhite/linuxcnc_debug.txt
and
    /home/owhite/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal

any thoughts?

Method 1 from here did not fix:
forum.linuxcnc.org/9-installing-linuxcnc...-installation#137159

I'll try the iso.

It was not meant to fix it, it is a much easier way to install on Mint.

Could be something to do with the Python3 work being done on master, I would stick with 2.8 at this stage unless there is something specific you need from master.

To be fair Python3, is stilla work in progress for LInuxcnc and a lot of PR's were pushed to master bracnh over the last few days.... It would be best to log an issue in git hub.
