Hi, This failure was a result of netcfg segfault seen on the logs.
------------------8<--------------->8---------------------------- Feb 24 06:31:51 netcfg[3724]: DEBUG: Writing wireless options for p4p1 Feb 24 06:31:51 netcfg[3724]: DEBUG: Success! Feb 24 06:31:52 main-menu[2545]: WARNING **: Configuring 'netcfg' failed with error code 139 Feb 24 06:31:52 main-menu[2545]: WARNING **: Menu item 'netcfg' failed. Feb 24 06:31:52 kernel: [ 62.915859] netcfg[3724]: segfault at 0 ip 00007f1ab154e34f sp 00007ffc781aec78 error 4 in libc.so.6[7f1ab14b1000+1ba000] ------------------8<--------------->8---------------------------- We have root caused a bug in the qede driver that was triggering this. qede IOCTL implementation returns '0' instead of -EOPNOTSUPP for all IOCTL requests made by user. wireless-lib used by netcfg as part of the PXE boot process tries learning whether our interface is wireless via sending an IOCTL; As we return '0', it learns we're a wireless interface and does some incorrect configurations. Later, netcfg would segfault due to broken information. Fixed qede IOCTL callback to return -EOPNOTSUPP to everything other than the timesync requests. Having said that, does netcfg also require a fix to gracefully fail in this case with a meaningful error message, rather than segfault so that it's easier to debug such issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667790 Title: PXE Installation Failure - Ubuntu14.04.5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1667790/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
