Hello, I want to apply a small patch, then test the new kernel. If it fails, I want to be able to return to my previous stable one.
Towards that end, I am following this guide: https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s4.2.2 That generally worked; the `test-patches` script incorporated my patch, compiled the kernel, and produced .deb files in the directory above. However, when I try to install the .deb it fails (apologies for poor line-wrapping, gmail is weak in this regard): $ sudo dpkg -i linux-image-4.19.0-5-amd64-unsigned_4.19.37-5+deb10u2a~test_amd64.deb [sudo] password for jrw: Selecting previously unselected package linux-image-4.19.0-5-amd64-unsigned. dpkg: considering removing linux-image-4.19.0-5-amd64 in favour of linux-image-4.19.0-5-amd64-unsigned ... dpkg: no, cannot proceed with removal of linux-image-4.19.0-5-amd64 (--auto-deconfigure will help): linux-image-amd64 depends on linux-image-4.19.0-5-amd64 linux-image-4.19.0-5-amd64 is to be removed. dpkg: regarding linux-image-4.19.0-5-amd64-unsigned_4.19.37-5+deb10u2a~test_amd64.deb containing linux-image-4.19.0-5-amd64-unsigned: linux-image-4.19.0-5-amd64-unsigned conflicts with linux-image-4.19.0-5-amd64 linux-image-4.19.0-5-amd64 (version 4.19.37-5+deb10u1) is present and installed. dpkg: error processing archive linux-image-4.19.0-5-amd64-unsigned_4.19.37-5+deb10u2a~test_amd64.deb (--install): conflicting packages - not installing linux-image-4.19.0-5-amd64-unsigned Errors were encountered while processing: linux-image-4.19.0-5-amd64-unsigned_4.19.37-5+deb10u2a~test_amd64.deb So, it seems that this "a~test" kernel is seen as conflicting with my current installed kernel. How do I overcome this? I assume this is an everyday task, but I'm not familiar enough to know what to tweak. Maybe I can make it use a fake version number (like "99.99") somewhere? Thanks -John
