This dep-symbols are usually provided by the kernel RPM itself. This helps picking the right kernel dependency, especially on RHEL-like system.</p> <p>In this case, you build a custom kernel yourself and I'm pretty sure your kernel rpm do not provide this extra Provides. You can check that in two ways:</p> <ul> <li>First, extract the provides list from your kernel package: &#8211;</li> </ul> <p> </p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> rpm -q --provides kernel-4.18.0-80.11.2.el8_lustre.aarch64 </pre> </div></div> <ul> <li>Second, try to force install your Lustre RPMS ignoring these missing deps. It should be usable.</li> </ul> <p>Is there any reason why you patched your kernel? A non-patched kernel is good enough for most usage and would avoid this issue.</p> <p> </p> <p> </p> Development Rank 1|i01wpb: Rank (Obsolete) 9223372036854775807
