It appears that the build fails because of the `/debian/debian.env` file. The contents of it changed recently in the 5.10. line (starting with 5.10.37) - but are OK before that and also in 5.12.x .
It is also noticeable that that "faulty" (?) commits/configs come from "kathleen" instead of "sita". 5.10.36 commit f0cc96561db7d294a8d39833e1ba90677191d18c Author: Kernel Builder (sita) <ubuntu-kernel-...@canonical.com> Date: Tue May 11 13:31:18 2021 +0000 diff --git a/debian/debian.env b/debian/debian.env +DEBIAN=debian.master 5.10.37 commit f3cf7622efde3cd18d3f4e70ee2bd69f8c764492 Author: Kernel Builder (kathleen) <ubuntu-kernel-...@canonical.com> Date: Fri May 14 09:34:35 2021 +0000 diff --git a/debian/debian.env b/debian/debian.env +DEBIAN=debian.master-21.10 5.10.39 commit a5637af073ffe933b864b9566b942c9e8c09d262 Author: Kernel Builder (kathleen) <ubuntu-kernel-...@canonical.com> Date: Sat May 22 10:33:45 2021 +0000 diff --git a/debian/debian.env b/debian/debian.env +DEBIAN=debian.master-21.10 5.12.6 commit 8e019e1f614023866e34a9b6b0b54ac6ab7cbf20 Author: Kernel Builder (sita) <ubuntu-kernel-...@canonical.com> Date: Sat May 22 10:33:33 2021 +0000 diff --git a/debian/debian.env b/debian/debian.env +DEBIAN=debian.master -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928535 Title: No disk space, mainline 5.10.37 and 5.11.20, 5.11.21 failed to build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1928535/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
