Hello. PKG_COMPRESS_FORMAT of FreeBSD-14 is tzst, so it doesn't seem to cause any problems. On FreeBSD-12.4-STABLE, poudriere cannot succeed pkg-repo because archive_write_add_filter_zstd returns ARCHIVE_WARN.
So which result does FreeBSD 13.x get? If you see a log like below, then there is a problem and work of poudriere may be wasted. pkg-static: zstd is supported, but not builtin Cannot create repository catalogue [00:00:17] Error: Failed to sign pkg repository There are still built packages in the .building directory, so let's collect them :) Regards.
