I can confirm this issue trying to build zfs 2.2.6 on Ubuntu 22.04. Build ends in
Unpacking of 'zfs-2.2.6-1.x86_64.rpm' failed at /usr/share/perl5/Alien/Package/Rpm.pm line 168. which can be narrowed down to the shell-out there doing rpm2cpio 'zfs-2.2.6-1.x86_64.rpm' | (cd zfs-2.2.6; cpio --extract --make-directories --no-absolute-filenames --preserve-modification-time) Splitting up that action into rpm2cpio zfs-2.2.6-1.x86_64.rpm > zfs-2.2.6-1.x86_64.cpio cpio --extract --make-directories --no-absolute-filenames --preserve-modification-time < zfs-2.2.6-1.x86_64.cpio confirms it's the cpio command that fails. Downgrading cpio to the non-security-update release version solves the issue and the build succeeds. apt install cpio=2.13+dfsg-7 Is this something that should be fixed in zfs or is it purely this cpio patch to blame? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2066157 Title: cpio 2.13+dfsg-2ubuntu0.4 breaks zfs build (alien command fails) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cpio/+bug/2066157/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
