Expand installation using WEB-based installer fails with the error: "Request for subsystem 'sftp' failed on channel '1'"

Article ID: 2190 
Last Review: Sep,25 2007
APPLIES TO:
  • Expand 2.x

SYMPTOMS

I opened https://expand-webinstall.swsoft.com/wui/, entered server IP and root password, pushed Start and the error occurred:

Error code #1002: AI distributive broken. Request for subsystem 'sftp' failed on channel '1'

CAUSE

Such error may occur if SFTP is disabled in SSH configuration.

RESOLUTION

Look at your /etc/openssh/sshd_config and check the line:

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

It should not be commented out with '#' sign.

Restart SSH after configuration file modification.
