Publickey agent specification being loaded as private key

[weberbr]

I use an agent which holds many private keys and specify which private key to use for which remote by specifying IdentityFile <key path>.pub per host in my ssh config. This setup appears to be currently broken or unsupported with sshfs. For example:

Given an ssh config:

Host myhost
    Hostname myhostname
    IdentityFile ~/.ssh/mykey.pub

and a minimal example:

import fsspec
with fsspec.open("ssh://myhost/myfile.txt") as f:
    f.read()

Gives the following traceback:

log.txt

It's not immediately clear to me whether the issue is here or in asyncssh

I did find a discussion regarding this upstream:
