If you face this kind of error message on a newly installed system you can use this workaround to solve that issue.
- boot on the install disk,
- mount the newly installed disk,
- create a
/usersfolder at the root of installed system,
- go to
/usersfolder on install disk,
- copy file
/usersfolder of installed system,
- umount the newly installed disk,
- reboot to the newly installed disk.
I done a not very well tested last change before building the ISO image that causes this problem.
