"sysctl.d docs clearly explain this is a known issue with clearly documented ways to work around it" Try googling "how to disable ipv6 in ubuntu".

[Bug 50093] Re: Some sysctls are ignored on boot
As procps has been replaced by systemd in recent releases (at least the sysctl service part), I'm switching the target package to systemd. Also, I'm changing this to wishlist as this isn't actually a bug; from the sysctl.d manpage: "Many sysctl parameters only become available when certain kernel modules are loaded. Modules are usually loaded on demand, e.g. when certain hardware is plugged in or network brought up. This means that systemd-sysctl.service(8) which runs during early boot will not configure such parameters if they become available after it has run. To set such parameters, it is recommended to add an udev(7) rule to set those parameters when they become available. Alternatively, a slightly simpler and less efficient option is to add the module to modules-load.d(5), causing it to be loaded statically before sysctl settings are applied (see example below)." ** Also affects: systemd (Ubuntu) Importance: Undecided Status: New ** Changed in: systemd (Ubuntu) Importance: Undecided => Wishlist ** Changed in: procps (Ubuntu) Status: Confirmed => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/50093 Title: Some sysctls are ignored on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/50093/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 50093] Re: Some sysctls are ignored on boot
Just to reiterate, I'm only marking procps as 'wontfix' because the sysctl service used in all current releases comes from systemd, *not* the procps package, so there is nothing to 'fix' in the procps package. Also, before people get upset, I've only marked this as Wishlist because the sysctl.d docs clearly explain this is a known issue with clearly documented ways to work around it. That doesn't mean i don't think this should be fixed; I absolutely do agree it should be fixed to properly apply all sysctl settings at boot, including for loadable modules loaded after boot. That will require upstream systemd work to implement, however, before backporting into Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/50093 Title: Some sysctls are ignored on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/50093/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have the same problem in Debian 9 Stretch, net.netfilter.nf_conntrack_max and net.nf_conntrack_max does not apply after reboot. The pure solution is load module nf_conntrack before sysctl.

I feel it's important to add that the very last comment (Stanley Sisneros (stanley-sisneros) wrote on 2018-05-30) is wrong, and the right workaround is by Tomasz Konefal (twkonefal-j) wrote on 2018-05-07.

A workaround for this that we're using now is to put the sysctl processing into crontab after reboot. e.g. @reboot root sleep 5 && sysctl --system Maybe one day someone will fix this bug :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/50093 Title: Some sysctls are ignored on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/50093/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
