Bug#963247: ignition-fuel-tools FTBFS with Protobuf 3.12.3

[László Böszörményi (GCS)]

Source: ignition-fuel-tools
Severity: normal
Justification: fails to build from source (but built successfully in the past)
Tags: upstream ftbfs

Hi,

Soon the Protobuf transition will start. Your package FTBFS with the Protobuf
3.12.3-1 version, currently in experimental. The relevant lines hopefully:

Please contact your upstream or try to fix yourself.
Probably your protobuf files only need to be regenerated.

Thanks,
