ID: 6932 Title: cmk-update-agent: Apply urllib3 bugfix Component: agents Level: 1 Class: Bug fix Version: 1.6.0i1 It has been observed recently that the agent updater might crash with an error message like <pre>IDNAError: The label ... is not a valid A-label</pre> The cause for this behavior is a bug in the underlying urllib3 python module. However, this has been fixed in a newer urrllib-version and hence we updated the underlying python modules to newer versions in order to apply the bugfix to cmk-update-agent.
