Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

The config file /usr/lib/sysctl.d/50-default.conf should come from systemd source package, and you can refer this upstream https://salsa.debian.org/systemd-team/systemd/-/blob/debian/master/sysctl.d/50-default.conf.

Until now, groovy also has the same problem but it's not really a big issue here.
