Overview

If installing the enterprise server on Linux fails and displays the message Unable to download JRE; please check network connection, the cause may be an old version of wget. The installer uses wget to download a compatible version of the JRE from Code42. Wget versions 1.14 and earlier do not support Server Name Indication (SNI), which is required to connect to Code42's download server.

Affects

Enterprise server on Linux devices using wget version 1.14 or earlier. To see what version of wget your system has, enter the command: wget -V

Recommended solution

To resolve this issue, follow the steps below:

  1. Update your version of wget to at least version 1.15 using your package manager. Depending on your Linux distribution, you might use one of these commands:
    • sudo apt-get install wget (Ubuntu)
    • sudo yum upgrade wget (Red Hat)
  2. Uninstall and reinstall your enterprise server.

Alternative solution

To resolve the issue without updating wget, follow the steps below to manually retrieve the required JRE:

  1. Uninstall the enterprise server.
  2. Download the Java 7 JRE, 64-Bit.
  3. Move the JRE tarball into the enterprise server installation folder.
  4. Use the installer downloaded in step 1 to reinstall the enterprise server.
    The enterprise server installer locates the JRE and installs successfully.
Update wget
The core problem is with older versions of wget, so if you follow the alternative solution without updating wget, you'll need to do this again the next time there's a enterprise server update.
