Comment 3 Lewkow Brigitte 2020-12-08 11:16:20 UTC 
Sure that's make awhile ! I don't even remember this report ! I sais it was not my computer then maybe it was a family member's one. If it the case, i was not even able to install anything (large amount of distros). All attempts of installing on that pc was terminated by errors on install, errors after install and more ! That made that pc (very competitive i5 core, 2G ram, ...) unusable, maybe for Redmond ? !!! A nightmare !!! Then i forgot even if it solved (?).
Please tell me wich status mention to set as i'm not a developper (nor geek) ;-)? 
Thanks !
