Bug description:
[ Impact ]
linux-firmware binary packages contain only compressed blobs. There's
no need to (re-) compress the binary debian packages. In fact
decompression at package installation time could cause problems which
results in package installation failures.
dpkg-deb (subproces): ZSTD_decompressStream error : Corrupted block
detected
[ Test Plan ]
Download binary debian packages and inspect them.
Uncompressed:
$ file linux-firmware_20241107.gitdb0082fa-0ubuntu1_amd64.deb
linux-firmware_20241107.gitdb0082fa-0ubuntu1_amd64.deb: Debian binary package
(format 2.0), with control.tar
Compressed:
$ file linux-firmware_20230915.gitdfa11466-0ubuntu1_amd64.deb
linux-firmware_20230915.gitdfa11466-0ubuntu1_amd64.deb: Debian binary package
(format 2.0), with control.tar.zst, data compression zst
[ Where Problems Could Occur ]
Problems would show up at package installation and/or upgrade time.
