Larry,

Have you only seen this bug on 1.21.3? Is it reproducible with 1.22? Do you see it with earlier versions of 1.21.x?

[Dimiter Naydenov (dimitern)]

This is the same issue as bug 1410876 why is this not a duplicate?

[Larry Michel (lmic)]

Mistakenly removed the duplicate. I am re-adding it.

[Larry Michel (lmic)]

Alexis,

Yes, we did see this issue with 1.21.1. Dimiter dupped this one to 1410876 which is for 1.20.13 but we see that the error messages are not quite the same and are raised from different locations in the function. One fails with lxc-wait and the other with lxc-clone.

"failed to retrieve the template to clone: error executing
          "lxc-wait": lxc_container: utils.c:...."

and

"agent-state-info: 'lxc container cloning failed: error executing "lxc-clone":
          lxc_container: utils.c:...."

I recall similar issue that was fixed in 1.22 beta but I will need to look for the bug number to see whether signature was exactly the same as this one.
