Hi
I'm wondering if anyone is able to use Tramp with a gpg smart card or a gpg agent that manages the ssh socket (so acts as an ssh agent)?
For me it fails with |file-error "Tramp failed to connect. If this happens repeatedly, try\n ‘M-x tramp-cleanup-this-connection’"))"|
I tried |tramp-cleanup-this-connection|, but no, that didn't help.Tramp seems to work locally - I am able to "sudo-this-file" and enter pin to unlock sudo (it's managed by the smart card U2F pam module).
Any suggestions how to approach debugging this would be very welcome. Debugger:|Debugger entered--Lisp error: (file-error "Tramp failed to connect.
