Would I expect some file or symlink matching *0aea4b30d53d7cc6386f1773a8dc8972793def1a* to exist in the filesystem, given I have what I think is the correct glibc debuginfo to be installed? Because it does *not* exist: $ find /usr -name '*0aea4b30d53d7cc6386f1773a8dc8972793def1a*' find: ‘/usr/share/polkit-1/rules.d’: Permission denied find: ‘/usr/share/selinux/targeted/default/active’: Permission denied find: ‘/usr/libexec/initscripts/legacy-actions/auditd’: Permission denied Does this indicate that I have the wrong glibc debuginfo installed? $ rpm -q glibc-debuginfo glibc-debuginfo-2.27.9000-35.fc29.x86_64 $ rpm -ql glibc-debuginfo | grep 0aea4b30d53d7cc [no output] Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com libguestfs lets you edit virtual machines.
