Comment 1 Guillaume GARDET 2020-03-19 16:09:35 UTC
It seems to be better now.
I will monitor next builds to see if still happens.
Comment 2 Guillaume GARDET 2020-06-03 10:19:40 UTC
It is much better those days. Lately, I did not spot any build failure related to this bug in Leap 15.2 with JeOS images.
Let's close it. I will reopen if it occurs again in Leap 15.2.
