Re: [Machinekit] machinekit.ini and MKUUID

[schoone...@gmail.com]

I have now uninstalled and re-installed several times on a spare Stretch partition, with and without a mkuuid file existing and cannot replicate your problem. It did remind me however of the arcane dpkg behaviour I noted when originally testing this. dpkg does not actually check the physical location for configuration files and assumes their existence unless you have removed the package with `apt purge <package-name>` So if you remove machinekit, it will leave the /etc/linuxcnc folder as is and assume it contains what it should do at next re-install. The safest way to update, if you are doing so frequently, is to create a 'clean slate' and do `apt purge machinekit*` It will not touch the /etc/linuxcnc/mkuuid file if you have one, because that is not part of the install manifest. However if a particular MKUUID is not important to you, delete that as well. The next re-install will copy machinekit.ini and rtapi.ini to /etc/linuxcnc and update the MKUUID in machinekit.ini to a unique one and then create a mkuuid file containing it so that you can update and retain the same MKUUID, if that matters. The sed line which errored is here in the postinst file https://github.com/machinekit/machinekit/blob/master/debian/machinekit.postinst#L87 The charactor 20 referred to is right on the divider between the search term and the replacement one, which makes me suspect that the first var had picked up a spurious char from the grep operation and it was interpreted as a line ending which terminated the sed operation prematurely. Hopefully if you purge and re-install you should have no further problems. regards On 18/02/19 07:39, schoone...@gmail.com wrote: There is nothing wrong with the sed command, can only assume there is some spurious char in one of the variables causing premature line termination. Go to /etc/linuxcnc and delete the mkuuid file and try again. That would have been created the last time you installed and may be corrupt.

I suspect the error is in the script that is supposed to edit mkuuid and machinekit.ini.

The dependency was missed for Stretch because it uses another control file. Should be built and in the repo by the end of the day. PR’s have been merged. So it should be available soon. Thanks for persisting, only with that info was I able to look in the right place.

Since machinekit now has to have a uuid generated the first time it is run, shouldn't uuid-runtime be part of the Machinekit requirements. It is, but we have no control over what other people put, or don't put, in their images. I didn't use an image.  I installed Debian from a netinstall ISO, set up the machinekit repo, and installed the machinekit package.  I did not notice the error message when it installed because apt continued on.  Afterward I needed to figure out what packaged I needed to install (uuid-runtime) to fix the errors when running Machinekit.
