The files /etc/ld.so.conf.d/i386-linux-gnu_EGL.conf and /etc/ld.so.conf.d/i386-linux-gnu_GL.conf are symlinks to /etc/alternatives/x86_64-linux-gnu_egl_conf /etc/alternatives/x86_64 -linux-gnu_gl_conf, which are in turn the symlinks to /usr/lib/virtualbox/additions/00vboxvideo.conf (from VirtualBox package).
Update-initramfs seems to have problems with symlinks (why?). Replacing the symbolic links with hard links (or just a copy of target file) resolves the warning, there is no need to remove the config files. Note that updates or reinstallation of VirtualBox will break the link, so this is not a permanent solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1800719 Title: missing conf files noted on apt upgrade after distribution upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1800719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
