Hello Daniel, or anyone else affected, Accepted systemd into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/229-4ubuntu21.28 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-xenial. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: systemd (Ubuntu Xenial) Status: In Progress => Fix Committed ** Tags added: verification-needed-xenial -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1862232 Title: Long hostname causes networking setup to fail Status in systemd: Fix Released Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: Fix Committed Status in systemd source package in Bionic: Fix Committed Bug description: [impact] networkd fails to bring up networking on systems with long hostname [test case] setting the hostname: $ sudo hostnamectl set-hostname asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf then reboot and check the networking.

[other info] the problem around this is that Linux sets HOST_NAME_MAX to 64, but RFC 1035 limits DNS labels to 63 characters, so any host with a max- length single-label hostname (i.e. a 64 character hostname with no dots) will be "valid" from Linux's perspective, but will violate RFC 1035 and thus systemd will consider it invalid and won't pass it to the dhcp server. Also note that a 64-character hostname that is *not* single-label (i.e. a hostname with at least 1 dot) will not cause this problem. The systemd patches continue to reject sending the invalid hostname to the dhcp server, but do not prevent networkd from finishing setting up networking.

[Touch-packages] [Bug 1862232] Re: Long hostname causes networking setup to fail
Hello Daniel, or anyone else affected, Accepted systemd into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/237-3ubuntu10.40 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-bionic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: systemd (Ubuntu Bionic) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-bionic -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1862232 Title: Long hostname causes networking setup to fail Status in systemd: Fix Released Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: In Progress Status in systemd source package in Bionic: Fix Committed Bug description: [impact] networkd fails to bring up networking on systems with long hostname [test case] setting the hostname: $ sudo hostnamectl set-hostname asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf then reboot and check the networking.
