SSH public key validation error (500) when creating LXC Container and adding ssh-key file

[Madhatter]

Hi, went back to install Proxmox 4.3-70 after some while to test the lxc.
However when creating an Ubuntu (16.04 and 14.04) LXC Container from a template downloaded through Storage content, and trying to add my id_rsa.pub ssh-key file using the "load SSH key file" button, at the end of the creation confirm tab, all I get is "SSH public key validation error (500)" being unable to create the container with the key. I need go back and use a password only.

It doesn't strike me as there is anything I could do fundamentally wrong and this is a killer feature to access the containers afaik.

Any suggestions please ? Thanks Andreas

Hi,
this seem an issue with ZFS and the way tempfiles are created.

/usr/share/perl5/PVE/Tools.pm uses O_TMPFILE. O_TMPFILE is an Linux Extension, which is not available under ZFS.

I think this is a bug and has to be fixed.

could you file a bug for this at bugzilla.proxmox.com ?

I'm having the same issue. Is there a known workaround yet?

you can make /tmp a tmpfs if you're on ZFS until a more permanent fix is on its way

That worked fine thanks a lot.
As requested above I open a bug on bugzilla
https://bugzilla.proxmox.com/show_bug.cgi?id=1188

ps: if anyone cares:
vi /etc/fstab
insert
tmpfs /tmp tmpfs nodiratime 0 0
