Package: src:alumet Version: 0.9.5+ds-2 Severity: serious Tags: ftbfs forky sid
Dear maintainer: During a rebuild of all packages in unstable, this package failed to build. [ Note: The build does not always fail, but the failure rate is around 80% here. As always, I can provide a VM to debug if required. ] Below you will find the last part of the build log (probably the most relevant part, but not necessarily). If required, the full build log is available here: https://people.debian.org/~sanvila/build-logs/202608/ About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you cannot reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. If this is really a bug in one of the build-depends, please use reassign and add an affects on src:alumet, so that this is still visible in the BTS web page for this package. Thanks. -------------------------------------------------------------------------------- [...] â 0 plugin disabled: ð 1 metric registered: - coffee_counter: U64 () ð¥ 1 source, ð 1 transform and ð 1 output registered. ð 0 metric listener registered.
