Comment 3 for bug 1726504

Thanks, Dimitri John Ledkov, for your kind interest in my report and for your remarks. It's not so easy to experiment with my system during (European) daytime, I need it to make a living.

I had not seen bug 1671760 before (the number is somehow reminiscent of the Beagle Boys, isn't it?); I now looked at it but fail to see anything familiar. Sorry.

I now did what I maybe should have done before – check for reproducibility. Unfortunately it is not a problem at all. When I comment out the “RemoveIPC=no” in /etc/systemd/logind.conf and reboot Linux, Oracle XE fails. When I restore the entry and reboot, Oracle XE works. Just logging out and in again does not change anything.

I have no backups of the /etc directory but I have a second PC which has not been updated to Ubuntu 17.10 (so the name is “artful”, thanks, but I never remember such names). The “RemoveIPC” line is commented out there as well, which confirms your assumption that nothing was changed on upgrade. But Oracle had no problems running on this machine. And I doubt that upgrading to Ubuntu 17.10 did in any way touch Oracle XE; certainly Ubuntu is not supposed to know anything about Oracle (on the contrary, to be Oracle-ignorant).

In my /var/log/apt/ directory there are term.log and history.log files. I suppose they are not of much help. It looks like the question is not so much “why did Oracle stop working” but “why did it work before.”

If it's evident that the treatment of RemoveIPC did not change between Zesty and Artful I can live with the changed RemoveIPC and would agree to close the bug.
