That's strange, I can also see this in my logs from back in April 2021,

As a shot in the dark, could you try the attached patch?  It's something
I added while looking at updating docker (I need to rebase this series
and get it committed). It's a bugfix, the patch-paths phase does not run
withouth it so it could be related to your issues. But for some strange
reason it's been working for me.
