But I am a Debianist (Debian/unstable AMD64 user). Best is to ask the Debian release-team or (if there exist) maintainers or responsibles for the IA64 port - which is an ***unofficial*** port. What I found... on : https://cdimage.debian.org/cdimage/ > Ports https://cdimage.debian.org/cdimage/ports/current/ https://cdimage.debian.org/cdimage/ports/current-debian-installer/ia64/debian-installer-images_20211020_ia64.tar.gz ^^ Last modified: 2021-10-20 22:52 https://cdimage.debian.org/cdimage/ports/current/debian-11.0.0-ia64-NETINST-1.iso ^^ Last modofied: 2022-03-28 14:18 With a net-install image you should be able to setup and explore the IA64 Debian cosmos. Example #1: binutils packages Checking available binutils package for Debian/unstable IA64 (version: 2.39.90.20230110-1): https://packages.debian.org/sid/binutils <--- Clearly states IA64 as "unofficial port" https://packages.debian.org/sid/ia64/binutils/filelist Example #2: linux-image packages Cannot say what this means... https://packages.debian.org/search?arch=amd64&keywords=linux-image (AMD64 - matches) https://packages.debian.org/search?arch=ia64&keywords=linux-image (IA64 - no matches) https://packages.debian.org/search?arch=ia64&keywords=linux (IA64 - matches - but no linux-image which ships normally a bootable Linux-kernel) As stated I have no expertise in Debian whatever release for IA64 arch. Hope that helps. -Sedat- _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
