I got a notice that something went wrong upgrade armv7-diskmount, and that I should report it here. I’ve created an account and I think I’ve uploaded the correct logs, but let me know if you need more info. Here are my apt logs: http://paste.osmc.tv/gipuvuxivu
Huh. I was quite sure I had switched back, but apparently I forgot. To those running into this topic later, I followed this guide, except that I apparently hadn’t run sudo rm /etc/apt/sources.list.d/a2dp.list as described there.
Thanks for the very prompt help Sam! I ran the command again and then did a manual install, and again received an error message, this time about armv7-udisks-osmc: logs. But otherwise it does not say there are any updates any more, so I guess it’s all good now?
