JeVois 1.10.0 Bug reports, full story, part 1
NB This forum has some limitations, so I had to devide this story into 4 parts.
I have 2 disks with Ubuntu LTS, 16.04 and 18.04 on same hardware, clean and just installed, w/o software or other legacy.
Fitst, I used JeVois 1.10.0 from deb repo.
Here are reports:
