AppsToGo: Using AppsToGo in Linux

This article gives some tips for those using AppsToGo in Ubuntu 20.04 with Firefox . It may be useful for other Linux variations. Users may need to do two things after installing Citrix Workspace.

Replace the Citrix certificates with a symbolic link to system certificates instead 

Execute the following in the terminal:

$ cd /opt/Citrix/ICAClient/keystore
$ sudo rm -rf cacerts
$ sudo ln -s /etc/ssl/certs cacerts

Disable IPv6 either temporarily or persistently

To immediately and temporarily disable IPv6

Execute the following in the terminal:

$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
$ sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1

IPv6 will be disabled for the user's system and AppsToGo should work until the next reboot.

To persistently (but reversibly) disable IPv6 across reboots

  1. Execute the following in the terminal: $ sudo gedit /etc/default/grub
  2. Find the line that says "GRUB_CMDLINE_LINUX_DEFAULT="
    • There may already be one or more options inside the quotations separated by spaces, e.g. "quiet splash" or nothing.
  3. Add the option ipv6.disable=1 separating it from other options by a space if necessary.
  4. Save the changes.
  5. Then execute: $ sudo update-grub

After rebooting, IPv6 should be persistently disabled and AppsToGo should work.

To enable IPv6 again 

  1. Remove the option.
  2. Update grub.
  3. Reboot.

Earlier versions of Ubuntu may recommend a different method for disabling IPv6.
