 When first launching on Linux in GUI mode you may encounter errors similar to `Namespace […] not available`, issues with the task bar icon display, or no browser popup when attempting to authorise your accounts.
 This is caused by missing dependencies for [pystray](https://github.com/moses-palmer/pystray/) and [pywebview](https://github.com/r0x0r/pywebview/), which are used to display the menu bar icon and authentication windows.
-See the [pywebview dependencies](https://pywebview.flowrl.com/guide/installation.html#dependencies) and [pystray FAQ](https://pystray.readthedocs.io/en/latest/faq.html) pages and [existing](https://github.com/simonrob/email-oauth2-proxy/issues/1#issuecomment-831746642) [closed](https://github.com/simonrob/email-oauth2-proxy/issues/136#issuecomment-1430417456) [issues](https://github.com/simonrob/email-oauth2-proxy/issues/305#issuecomment-2482989955) in this repository for a summary and suggestions about how to resolve this.

 A similar issue may occur on Windows with the [pythonnet](https://github.com/pythonnet/pythonnet) package, which is required by [pywebview](https://github.com/r0x0r/pywebview).
 The [pythonnet installation instructions](https://github.com/pythonnet/pythonnet/wiki/Installation) may offer alternative ways to install this package if the default installation fails.
