I have tried to install over 8 ties now on 3 different machines and in every instance after about the third boot I get...
init:job process C:529 Unhandled error from job_process_spawn : Permission denied
Init:....... mountall shell main process : permission denied
Same in recovery mode.
I did a base install plus updates plus Nvidia driver +Inkscape, Pysdm, Smb4K , nothing exotic. I have tried installing same programmes with Debian and OpenSuse and yes, Ubuntu with no apparent problem.
