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.
