Fix 202408002

Description of the Inconsistency or Failure​

Apache Ambari displays the error configparser.InterpolationSyntaxError when attempting to download installation packages.

The issue was caused by the configparser's variable interpolation, which doesn't handle special characters in URLs well, such as %40 (representation of @) used for authentication credentials.

Affected Services and Components​

  • Ambari 3.0.0.0: Ambari Web
  • AMBARI-7907

Impact​

It is not possible to download Apache Ambari installation packages when the repository URL contains special characters, thus requiring the creation of a local package repository.

Required Actions​
