[follow up on #956299] Hi Dmitry,
I was preparing gitaly 12.9.2 (gitaly master branch) and was building fine till yesterday but started ftbfs from today. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=956299 for error message.
I cannot upload newer gitaly to unstable till rails 6 migration starts (ruby component of gitaly depends on rails) so you did not see the build dependency (the version in unstable vendors grpc). I don't know if there is an easy way to check if a version in experimental is in build depends.
Can you help fix the failure? Also it will be helpful if you can consider gitaly in experimental for future updates.
Thanks Praveen
