Upgrade Instructions

• First update the webwork2 and pg code. For this run

  > cd /opt/webwork/webwork2

  > git fetch origin

  > git checkout WeBWorK-2.19

  > git pull

  > cd /opt/webwork/pg

  > git fetch origin

  > git checkout PG-2.19

  > git pull

  Note: Will use the main branches after the release.

• Update the javascript and css assets for webwork2 and pg with

  > cd /opt/webwork/webwork2/htdocs

  > npm ci

  > cd /opt/webwork/pg/htdocs

  > npm ci

• The following perl packages will need to be installed (run bin/check_modules.pl to ensure you have all programs/modules)
  • Archive::Zip::SimpleZip (on Ubuntu install from cpan)
  • File::Copy::Recursive (on Ubuntu install libfile-copy-recursive-perl)
  • GD::Barcode::QRcode (on Ubuntu install libgd-barcode-perl)
  • MIME::Base32 (on Ubuntu install libmime-base32-perl)
  • SQL::Abstract (on Ubuntu install libsql-abstract-perl)
• The program inkscape is needed for conversion of svg to png for hardcopy. This is used indirectly by imagemagick's convert program. The imagemagick program may need special configuration for some operating systems to use inkscape for this. (On Ubuntu install the inkscape package with apt. No further configuration is needed.)
• Compare any files in the /opt/webwork/webwork2/conf directory that have been copied from a .dist file to the updated distribution .dist file, and update as needed.
  • In particular make sure that the variable $admin_course_id is defined in site.conf.
  • Note that two factor authentication is enabled for all courses by default. This only affects signing in with a username and password on the login page, and not remote authentication methods. See the $twoFA variables in localOverrides.conf on how to configure two factor authentication.
  • If the setting for secrets in your webwork2.mojolicious.yml file is the same as that in the webwork2.mojolcious.dist.yml file, then make sure that you change it. That is now used to sign cookies, and would be a security vulnerability to use the default from the distribution.
• restart the webwork2 server: >sudo systemctl restart webwork2
• Upgrade the admin course by executing the upgrade_admin_db.pl script.
• Make sure to upgrade courses from the admin course to relegate changes to the database.
