Hello Jonas, I’ve also recently hit an error during the do_patch task of libselinux. 001-Fix-NULL-pointer-use-in-selinux_restorecon_set_sehandle.patch has been recently added to the dunfell branch but fails to apply: ERROR: Applying patch '0001-Fix-NULL-pointer-use-in-selinux_restorecon_set_sehandle.patch' on target directory '/yocto/c2100-catchpoint-system-image/poky/build/tmp/work/core2-64-poky-linux/libselinux/3.0-r0/libselinux-3.0' Command Error: 'quilt --quiltrc /yocto/c2100-catchpoint-system-image/poky/build/tmp/work/core2-64-poky-linux/libselinux/3.0-r0/recipe-sysroot-native/etc/quiltrc push' exited with 0 Output: Applying patch 0001-Fix-NULL-pointer-use-in-selinux_restorecon_set_sehandle.patch can't find file to patch at input line 22 Perhaps you used the wrong -p or --strip option?
