At the moment, Scarthgap does not officially support CentOS Stream 9 as a host distribution (see: https://docs.yoctoproject.org/5.0.15/ref-manual/system-requirements.html#supported-linux-distributions). This prevents our development team from running the Yocto build system in our standard corporate Linux environment, where CentOS Stream 9 is the (only) approved platform. Expected outcome: official inclusion of CentOS Stream 9 in the list of supported host distributions. Below is the system kernel information, with any sensitive identifiers removed: Linux <redacted-hostname> 5.14.0-598.el9.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Jul 8 16:37:49 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux 104140 1 paul 2026-02-03 13:22:05 +0000 Hi Alessandro, We do support AlmaLinux 9 and Rocky Linux 9 for scarthgap, these are similar to CentOS Stream 9 so I expect that a build should probably work. Are you seeing any specific issues or failures? We'll discuss whether we can extend our testing to include CentOS Stream 9 for Scarthgap. Thanks! 104141 2 alessandro.quirile 2026-02-03 13:39:59 +0000 Hello Paul, Thanks for your feedback. I tried building core-image-minimal, but I am hitting several failures in the build (all during do_recipe_qa for multiple native recipes). The full log is available here: https://friendpaste.com/1Z90Gl1rv8p2GMEujgL1Ga The build stops with repeated errors like this: ERROR: texinfo-dummy-native-1.0-r0 do_recipe_qa: zstd: can't stat 8 : No such file or directory tar: Child returned status 1 This happens consistently across several native recipes (texinfo-dummy-native, gettext-minimal-native, quilt-native, m4-native, libtool-native, autoconf-native, automake-native, xz-native, etc.). I’m not applying any custom layers or modifications: this is a clean Scarthgap checkout. Let me know if you need additional information or if I can help with further testing on CentOS Stream 9. Thanks! 104154 3 paul 2026-02-05 09:27:26 +0000 Hi Alessandro, I have a few questions to help us narrow down the issue. I'll also run some tests on Stream 9 on our autobuilder if I can. Do you have any modifications in site.conf or local.conf? Do you know of any relevant changes to the CentOS Stream 9 config, e.g. selinux profile, etc? Are the system packages up-to-date? Have you previously had successful builds with Scarthgap on this system? If so, do you know if the issues started with a system package upgrade or by updating the Yocto layers? Do you see the same issues if you use the latest commit on the scarthgap branch (d50e4680ed6f930582d907b37c9ed545a89f5c27 in poky)? 104155 4 paul 2026-02-05 09:31:09 +0000 Sorry, I pasted the OE-core commit.... the latest commit in poky is 353491479086e8d3f209d5cce0019a29e143b064 which I think you're already using based on the build log you shared. 104156 5 alessandro.quirile 2026-02-05 11:43:32 +0000 Hello Paul, I do not have any relevant modifications in poky/build/conf/local.conf file (see: https://friendpaste.com/iQmqYjJuEQYxTFLuwJuEM) My system packages are all up-to-date. I do not know any relevant changes to the CentOS Stream 9 config, e.g. selinux profile. I have never had previous succesful builds with Scarthgap on this system. Thank you. 104164 6 randy.macleod 2026-02-05 15:46:01 +0000 We'll try Centos Stream 9 builds on the YP autobuilder and if that works, we *may* add it to the supported list and documentation but we may need help to get this supported if there are problems. 104193 7 alessandro.quirile 2026-02-09 08:34:55 +0000 Thank you. Just let me know whether this platform will be supported or not 104198 8 alessandro.quirile 2026-02-09 10:30:49 +0000 Do you have any idea about the time this activity is going to take? 104233 9 paul 2026-02-11 16:16:58 +0000 Hi Alessandro, We have an upcoming release build for Scarthgap 5.0.16, once that is built we will enable Scarthgap builds on the stream9 worker and run some testing. Hopefully this will allow us to declare compatibility with Scarthgap in the 5.0.17 release in March. 104241 10 yoann.congal 2026-02-12 09:05:48 +0000 Note: #16143 "AB-INT: do_image_wic: tar command return exit status 2" will most likely be seen on scarthgap/stream9 104550 11 yoann.congal 2026-03-06 12:54:42 +0000 (In reply to Yoann Congal from comment #10) > Note: #16143 "AB-INT: do_image_wic: tar command return exit status 2" will > most likely be seen on scarthgap/stream9 Those are now fixed on scarthgap.

There was a mistake made when adding the LSB string in the poky.conf distro configuration file. It can be fixed by applying patch [1]. I expect it to be fixed soon on the scarthgap branch.
