bug#34335: 27.0.50; Tramp ssh hangs

John Shahid

After pulling the recent Emacs master, I cannot use tramp with the ssh
anymore.  When I try to use it, Emacs just hangs until I quit
(i.e. C-g).  Attached tramp logs with 'tramp-verbose' set to 10.  I
tried this twice and attached the logs from both attempts.

Thanks! Do you have a chance to send also tramp-verbose 10 logs from an
earlier build of Emacs, which worked?

Just being curious: have you tried, whether it works with "emacs -Q"?

Best regards, Michael.

Well, "emacs -Q" works as expected.  Apologies for not trying this out
early.  I just assumed it was a bug since my current config work with a
previous commit.  I will try to figure out what is going on and report
back.

Cheers,

JS

Actually, Emacs work with my config as expected.  I'm not sure why that
was failing yesterday tbh.  Probably PEBKC.

I think this bug can be closed, I will open a new one if I run into any
issues.  Sorry again for the noise.

Cheers,

JS

Thanks for reporting, I was already running out of ideas what could be
the problem. And no problem for the false alarm; usually it's *me* who
breaks something.

I'm closing the bug.
