Comment 2 Richard Purdie 2022-01-17 16:48:14 UTC 
I think these can happen when the file is being written by two writers and it sees an incomplete file, or the file is being accessed before it was completely written out. This therefore could be some kind of race in ruby's makefiles?
Comment 3 Alexandre Belloni 2022-01-17 17:06:00 UTC 
The ruby workdir is saved in /srv/autobuilder/autobuilder.yocto.io/pub/failed-builds-data/bug14695

Running do_install again on the worker after renaming the build directory properly just worked.
Comment 6 Randy MacLeod 2022-01-20 15:45:35 UTC 
This seems to have started after December's ruby upgrade.
Comment 7 Alexander Kanavin 2022-01-20 15:52:59 UTC 
Konrad, would you be able to take a look?
Comment 8 Alexander Kanavin 2022-01-20 22:24:34 UTC 
Patch proposed:
https://lists.openembedded.org/g/openembedded-core/message/160802

Note that *not* enabling libruby.so is the upstream default.
