Public bug reported: There is a script (/etc/resolvconf/update-libc.d/squid) provided by the squid package which calls:
invoke-rc.d reload squid || true The thing is, that command somehow does not cause the squid to reload. This is particularly painful when Ubuntu is being contained in VirtualBox and some resolv.conf changes are done during the boot process. I.e. after the system boot the squid proxy server is just not working (it returns HTTP/500 and HTTP header X-Squid-Error: ERR_CANNOT_FORWARD). In access log one can see something like this: 1518190105.150 0 127.0.0.1 TCP_MISS/500 4495 GET http://security.ubuntu.com/ubuntu/dists/artful-security/InRelease - HIER_NONE/- text/html 1518190105.153 0 127.0.0.1 TCP_MISS/500 4474 GET http://pl.archive.ubuntu.com/ubuntu/dists/artful/InRelease - HIER_NONE/- text/html I.e. HIER_NONE appears practically after 0 miliseconds means that squid is experiencing connectivity problems. That being said, reloading squid using systemd equivalent of the invoke- rc.d command works just fine (in the script also): systemctl reload squid || true So, to sum up, I would like to ask to fix the squid package by either: * Change /etc/resolvconf/update-libc.d/squid to use `systemctl reload squid` * Make `invoke-rc.d reload` work properly for squid Environment: Description: Ubuntu 17.10 Release: 17.10 squid: Installed: 3.5.23-5ubuntu1.1 Candidate: 3.5.23-5ubuntu1.1 ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: squid 3.5.23-5ubuntu1.1 ProcVersionSignature: Ubuntu 4.13.0-32.35-generic 4.13.13 Uname: Linux 4.13.0-32-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 CurrentDesktop: KDE Date: Fri Feb 9 17:03:47 2018 InstallationDate: Installed on 2016-08-03 (555 days ago) InstallationMedia: Kubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) SourcePackage: squid3 UpgradeStatus: Upgraded to artful on 2017-10-05 (127 days ago) mtime.conffile..etc.squid.squid.conf: 2017-11-27T19:29:36.332000 ** Affects: squid3 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug artful ** Patch added: "Proposed fix: use systemd in /etc/resolvconf/update-libc.d/squid" https://bugs.launchpad.net/bugs/1748471/+attachment/5051932/+files/squid.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748471 Title: Automatic squid reload on resolv.conf update does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid3/+bug/1748471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
