Could any one help please

I’m sorry but given the recent actions from Canonical regarding LXD:

We really can’t be providing support to LXD users on this forum anymore.

You may want to consider switching to Incus instead, or if you’d like to stay on LXD, you should reach out on the Canonical forum instead.

Sorry about that!

@stgraber Thanks for letting me know about lxd’s state.

I have uninstalled lxd and i have installed incus.

However I am still facing the same issue.

I have raised an issue

please close this lxd issue
