@Billy thanks for the Xenial xl2tpd test package. I setup an Ubuntu 16.04.4 VM which came with kernel 4.13.0-36-generic and did an apt update followed by an apt upgrade and it installed kernel 4.15.0-29-generic. I didn't know the proper way to downgrade to kernel 4.4, so manually downloaded and installed the following :
linux-headers-4.4.0-124_4.4.0-124.148_all.deb linux-headers-4.4.0-124-generic_4.4.0-124.148_amd64.deb linux-image-4.4.0-124-generic_4.4.0-124.148_amd64.deb Following is a summary of the tests performed, first with unpatched xl2tpd followed by the test PPA xl2tpd. Ubuntu 16.04.4 with xl2tpd-1.3.6+dfsg-4ubuntu0.16.04.1 : * didn't check kernel 4.4.0-124-generic. * kernel 4.13.0-36-generic - works as expected. * kernel 4.15.0-29-generic - results in following error as expected : xl2tpd[2189]: udp_xmit failed ... with err=-1:No such device Ubuntu 16.04.4 upgrade to xl2tpd-1.3.6+dfsg-4ubuntu0.16.04.1+lp1760796 : * kernel 4.4.0-124-generic - works! * kernel 4.13.0-36-generic - works! * kernel 4.15.0-29-generic - works! So things look okay to me in regards to xenial. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760796 Title: kernel 4.15 breaks xl2tpd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xl2tpd/+bug/1760796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
