Thanks for the report, I can see that Docker Hub builds of develop are also failing, likely in a similar way. (Though release builds are working.) I'll take a look soon, hopefully on Monday.

Docker Hub develop builds are working again, so I assume this also fixes the issue for reporters here as well, but do let us know if there's further trouble.
