Re: How to access private channel

[Lo Peter <peterloleungyau@gmail.com>]

After some googling, I found two related bug reports of libssh2:
https://github.com/libgit2/pygit2/issues/1013
https://github.com/saltstack/salt/issues/57121

I guess Guix uses libssh2 to process private channels over SSH, if so,
I think doing guix pull first would encounter the same problem.

The suggested workaround is to generate a SSH key in the older PEM
format using the "-m PEM" option of ssh-keygen.
I have tried the workaround and it works for me.

Regards,
Peter Lo
