[ovirt-users] stty: standard tty: inappropriate ioctl for device

I'd like to share this with the list because its something that I changed for convenience, in .bashrc, but had a not so obvious rippling impact on the ovirt self hosted installer. I could imagine a few others doing this too and I'd rather save future them hours of google time Every install failed no matter what and it was always at the SSO step to revoke token (here: https://github.com/machacekondra/ansible/blob/71547905fab67a876450f95c9ca...) and then reissue new token but the engine log yielded different information. The SSO failure was a red herring engine.log:2020-05-04 22:09:17,150-04 ERROR [org.ovirt.engine.core.bll.hostdeploy.InstallVdsInternalCommand] (EE-ManagedThreadFactory-engine-Thread-1) [61038b68] Host installation failed for host '672be551-9259-4d2d-823d-07f586b4e0f1', 'node1': Unexpected error during execution: stty: standard input: Inappropriate ioctl for device engine.log:2020-05-04 22:09:17,145-04 ERROR [org.ovirt.engine.core.uutils.ssh.SSHDialog] (EE-ManagedThreadFactory-engine-Thread-1) [61038b68] SSH error running command root@node1:'umask 0077; MYTMP="$(TMPDIR="${OVIRT_TMPDIR}" mktemp -d -t ovirt-XXXXXXXXXX)"; trap "chmod -R u+rwX \"${MYTMP}\" > /dev/null 2>&1; rm -fr \"${MYTMP}\" > /dev/null 2>&1" 0; tar --warning=no-timestamp -C "${MYTMP}" -x && "${MYTMP}"/ovirt-host-deploy DIALOG/dialect=str:machine DIALOG/customization=bool:True': RuntimeException: Unexpected error during execution: stty: standard input: Inappropriate ioctl for device I was on the hunt for this for the better part of 2 days or so, because who else has anything to do during quarantine, wracking my brain and trying everything to figure out what was going on Well, it was my own fault # cat .bashrc | grep -i stty stty erase ^? With this set in the .bashrc of the node I was running the installer via cockpit from, ovirt installer will fail to install This was set for convenience to have backspace work in vim since at some point it stopped working for me Should I file this as a bug? The message generated is more of a warning then a failure but I do not know the internals of ovirt like that. Commands still actually execute fine ovirt-engine(a)192.168.222.84) # ssh 10.0.16.221 "uptime" root(a)10.0.16.221's password: stty: standard input: Inappropriate ioctl for device 22:30:01 up 22:45, 2 users, load average: 0.80, 0.62, 0.80 One thing I think should be called out in the docs, and called out very loud, is that the entire ovirt installer expects a clean 110% machine that is done right after install and provided and IP and hostname. Its not that obvious, but it is now
