openssh-sftp-server is installed in /usr/lib/openssh while openssh-server expects it in
/usr/lib/ssh. Consequentially, any client using sftp gets an EOF and closes "unexpectedly".

Workaround: cd /usr/lib; ln -s openssh ssh

Err ... but it doesn't.  Here's the default configuration as shipped by
the openssh-server package:

  sshd_config:Subsystem   sftp    /usr/lib/openssh/sftp-server

Perhaps you modified your /etc/ssh/sshd_config and didn't notice?

Thanks! Some old script seems to do the same change over and over - someone
had copied that piece of config somewhere. Since openssh is also known as
'ssh' to the Debian system, wouldn't it be a good idea to introduce a
compatibility link, since scripts couldn't determine the proper config line
by themselves...?

I'm not sure it's sensible to introduce compatibility links for every
possible typoed version of a path.  sftp-server has never been installed
as /usr/lib/ssh/sftp-server in Debian; it was previously
/usr/lib/sftp-server, and I've kept a compatibility symlink for that for
over 12 years, but it's never been in /usr/lib/ssh/.

What is the old script in question at your site?
