Public Linux Environment: Manually Install or Update a WordPress Plugin

Who needs to do this?

Anyone hosting a website on the Public Linux / Volweb server (sites hosted on
Note: Those running a site with a Custom / Vanity URL ( do not need to follow the manual steps. They may continue to update their website(s) through the WordPress dashboard.

Why does this need to be done?

Two-factor authentication is in place across most university technologies and is now required on the OIT Public Linux servers. Due to this change, Volweb sites running WordPress can no longer perform WordPress, plugin, and theme updates through the WordPress dashboard. Volweb-hosted sites (websites with the URL “”) require a manual update process to securely access the UT Public Linux environment. Perform WordPress updates by connecting to the Linux server through a Secure File Transfer Protocol (SFTP) client (preferred) or Secure Shell Host (SSH). 

The 2FA changes will affect your WordPress site in two ways:

  1. WordPress updates cannot be made through the WordPress dashboard.
  2. Plugin and Theme installations/updates cannot be made through the WordPress dashboard.

How often do WordPress updates need to be done?

It is good practice to schedule monthly or semesterly maintenance and security checks by logging into WordPress and checking the Dashboard. Check for a red dot next to the Updates button in the Dashboard altering you that there are updates to plugins.

Items to prepare beforehand

  1. Have your login information at hand.
    1. You will need your UT NetID & password to log into your Public Linux account.
    2. You will need your unique Volweb / WordPress username and password to log into your WordPress dashboard ( Your username is likely to be your UT email. If you need to reset your password, select “Lost your password?” and follow the prompts.
  2. Be sure you have an SSH/SFTP client (preferred) or working knowledge of Secure Shell. SSH (Secure Shell) and SFTP (SSH File Transfer Protocol) clients are applications used to securely transfer files to a server, and usually look very similar to the folder structure on your computer.
