If you install sufficiently old virtualbox (ie the oldest you can find) you get the old kABI version and an old kernel. With this you can reproduce the issue. There was a workaround added for kernels on which a package might depend and the kernel is removed from the list of kernels to remove when something depends on it. This however does not work if something depends on the kernel indirectly: old kernel - old kmp - old virtualbox In this case attempt to remove the kernel triggers removing the kmp and attempt removing the kmp fails because virtualbox depends on it. The old kmp is removed from the list of packages to remove and the operation is retried. However, the old kernel is still on the list of packages to remove and attempting to remove it adds the old kmp as well. -- You are receiving this mail because: You are on the CC list for the bug.

TL;DR: It all works as designed.

# uncomment and edit the "multiversion" settings in zypp.conf, like this: $ grep ^multiversion /etc/zypp/zypp.conf multiversion = provides:multiversion(kernel) multiversion.kernels = latest,latest-1,running # install test package with patch from Michal $ zypper in mkinitrd-2.4.2-106.12.1.x86_64.rpm # add SLE11-SP3 repo to simulate a system with old kernels $ zypper ar http://dist.suse.de/update/build-ncc.suse.de/SUSE/Updates/SLE-SERVER/11-SP3/... sp3-update # install a test package that requires "xen-kmp-default" $ zypper in ineed-0.1-2.1.noarch.rpm # install two kernels from SLE-11-SP3 (running kernel is SP4 one). $ rpm -qa kernel-default-base kernel-default xen-kmp-default | sort kernel-default-base-3.0.101-0.8.1 kernel-default-base-3.0.101-0.15.1 kernel-default-base-3.0.101-63.1 kernel-default-3.0.101-0.8.1 kernel-default-3.0.101-0.15.1 kernel-default-3.0.101-63.1 xen-kmp-default-4.2.3_02_3.0.101_0.8-0.7.9 $ rpm -q --whatrequires xen-kmp-default ineed-0.1-2.1

Now purge-kernels should uninstall the oldest kernel, as the requirements of xen-kmp-default are met by the latest-1 kernel (3.0.101-0.15.1). This succeeds:

$ /sbin/purge-kernels Removed: kernel-default-base-3.0.101-0.8.1.x86_64 kernel-default-3.0.101-0.8.1.x86_64 $ /sbin/purge-kernels /sbin/purge-kernels: Nothing to do.

Now I remove "latest-1" from the multiversion configuration.

$ sed -i 's/multiversion.kernels = latest,latest-1,running/multiversion.kernels = latest,running/' /etc/zypp/zypp.conf $ grep ^multiversion.kernels /etc/zypp/zypp.conf multiversion.kernels = latest,running $ /sbin/purge-kernels error: Failed dependencies: xen-kmp-default is needed by (installed) ineed-0.1-2.1.noarch /sbin/purge-kernels: giving up.

This is expected because of the ineed -> xen-kmp-default -> kernel-default-base- 3.0.101-0.8.1.x86_64 dependency chain. Note that this happens only if a newer xen-kmp-default package (for the SP4 kernel) is not installed. If I install that package, the SP3 kernel can be uninstalled:

$ zypper in xen-kmp-default-4.4.2_08_3.0.101_63-1.7.x86_64 $ rpm -qa kernel-default-base kernel-default xen-kmp-default|sort kernel-default-3.0.101-0.15.1 kernel-default-3.0.101-63.1 kernel-default-base-3.0.101-0.15.1 kernel-default-base-3.0.101-63.1 xen-kmp-default-4.2.3_02_3.0.101_0.8-0.7.9 xen-kmp-default-4.4.2_08_3.0.101_63-1.7 $ /sbin/purge-kernels Removed: kernel-default-3.0.101-0.15.1.x86_64 kernel-default-base-3.0.101-0.15.1.x86_64 xen-kmp-default-4.2.3_02_3.0.101_0.8-0.7.9.x86_64

...

$ /sbin/purge-kernels error: Failed dependencies: xen-kmp-default is needed by (installed) ineed-0.1-2.1.noarch /sbin/purge-kernels: giving up.

This is expected because of the ineed -> xen-kmp-default -> kernel-default-base- 3.0.101-0.8.1.x86_64 dependency chain.

I was wrong here - this was not expected. Rather than "giving up", purge-kernels should detect the situation and exit with success status. The end result (kernel and KMP not being uninstalled) would be the same. -- You are receiving this mail because: You are on the CC list for the bug.
