Going through some experiments: Simple install/deinstall: $ sudo dpkg -i linux-image-2.6.28-1-ub-generic_2.6.28-1.1_amd64.deb [...] $ sudo dpkg -r linux-image-2.6.28-1-ub-generic [...] $ ls /lib/modules/2.6.28-1-ub-generic modules.alias modules.inputmap modules.pcimap modules.usbmap modules.ccwmap modules.isapnpmap modules.seriomap modules.ieee1394map modules.ofmap modules.symbols
Simple install/Purge: $ sudo dpkg -i linux-image-2.6.28-1-ub-generic_2.6.28-1.1_amd64.deb [...] $ sudo dpkg -P linux-image-2.6.28-1-ub-generic [...] rmdir: failed to remove `/lib/modules/2.6.28-1-ub-generic': Directory not empty dpkg - warning: while removing linux-image-2.6.28-1-ub-generic, directory `/lib/modules/2.6.28-1-ub-generic' not empty so not removed. $ ls /lib/modules/2.6.28-1-ub-generic modules.seriomap Fixing up the postrm so it purges the modules.seriomap: $ sudo dpkg -i linux-image-2.6.28-1-ub-generic_2.6.28-1.1_amd64.deb [...] $ sudo dpkg -P linux-image-2.6.28-1-ub-generic [...] $ ls /lib/modules/2.6.28-1-ub-generic ls: cannot access /lib/modules/2.6.28-1-ub-generic: No such file or directory Something is clearly wrong with the postrm purge support. We are unconditionally removing the directory regardless of the fact its completely reasonable for there to be files from other packages (headers, source etc) in this directory. Looking at it closely it only seems to work that way because the dependancy map files modules.*map are treated as configuration files. But actually they are not. We are completely happy to remove the main member of this collection modules.map in the normal remove and on a reinstall we simply overwrite the lot of them, no user modification is expected; nor does it appear sensible. Put together a patch to clean this lot up (attached). With the patched prerm/postrm: $ sudo dpkg -i linux-image-2.6.28-1-ub-generic_2.6.28-1.1_amd64.deb [...] $ sudo dpkg -i linux-headers-2.6.28-1-ub [...] $ ls /lib/modules/2.6.28-1-ub-generic build modules.alias modules.ieee1394map modules.ofmap modules.symbols initrd modules.ccwmap modules.inputmap modules.pcimap modules.usbmap kernel modules.dep modules.isapnpmap modules.seriomap $ sudo dpkg -P linux-image-2.6.28-1-ub-generic [...] $ ls /lib/modules/2.6.28-1-ub-generic build $ sudo dpkg -r linux-headers-2.6.28-1-ub-generic [...] $ ls /lib/modules/2.6.28-1-ub-generic ls: cannot access /lib/modules/2.6.28-1-ub-generic: No such file or directory Much more believable. Will push this up for review. ** Attachment added: "0001-UBUNTU-clean-up-module-dependancy-information-on-pa.patch" http://launchpadlibrarian.net/20204061/0001-UBUNTU-clean-up-module-dependancy-information-on-pa.patch -- Removal does not clean up after dkms, l-r-m(?) https://bugs.launchpad.net/bugs/300773 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
