Announcements

End of support for Synthetic-enabled ActiveGate on Ubuntu 18.04

Digital Experience | Synthetic Monitoring

Chromium development for Ubuntu 18.04 stopped at version 112. For important security and performance reasons, we’ve decided to discontinue our support for installing Synthetic-enabled ActiveGate on Ubuntu 18 after ActiveGate version 1.283.

ActiveGate version 1.283 was the last Synthetic-enabled ActiveGate supported on Ubuntu 18. Additionally, with Dynatrace version 1.284, we have introduced mechanisms preventing Synthetic-enabled ActiveGates on Ubuntu 18 from being updated beyond version 1.283.
