The error in the logs indicates there is at least one repository configured via the legacy Light SCM plugin, which has been configured by following these steps:
Go to Administration > Repositories.
Click the Plugins tab.
Go to in Configure Plugin... under the FileSystem [LightSCM] tab.
Add a repository.
Enter anything for the Name and Base Path values.
Save.
Reload the repositories list in the Administration panel after following these steps will lead to this error.
Cause
This is a confirmed bug in 4.8.9 that was introduced by a recent upgrade of the XStream library, and it will be fixed in 4.8.10
