[Bug 1450085] Re: kio_sftp can't connect to hosts after OpenSSH 6 has cached their ECDSA key

 

I remember that upstream bug. No, this should be a new one. That bug was fixed.
Now, sftp://servername in Dolphin shows this message:

The host key for this server was not found, but another type of key
exists. An attacker might change the default server key to confuse your
client into thinking the key does not exists. Please contact your system
administrator.

Title:
  kio_sftp can't connect to hosts after OpenSSH 6 has cached their ECDSA
  key

Status in kde-runtime package in Ubuntu:
  Confirmed

Bug description:
  This seems to be the KDE bug 270322 -
  https://bugs.kde.org/show_bug.cgi?id=270322, which is supposedly fixed
  upstream, in libssh, whose version 0.6.0 supposed to have this bug
  fixed.

  Ubuntu 15.04 ships libssh 0.6.3, but we still have the behavior that
  using Dolphin to access SFTP URLs, after using OpenSSH to cache the
  host's ECDSA key result in "The host key for this server was not
  found, but another type of key exists." error and inability to
  connect.

  The workaround details in the KDE bug works, so it seems like the same
  problem.
