Could you try adding dtoverlay=mmc to your /boot/config.txt ?
There is a change in the sd card driver, if that fixes it for you, you likely have one of those incompatible cards.
If so … please mention your brand and model of the sd card right here.
I can understand your frustration but it’s not ‘broken’
In the last few days I have created new builds for a Pi2 and tested out a few different microSD cards and the installation and updates have worked fine. I was even impressed that it detected the Edimax wireless dongle without issues too.
FYI I used the ‘OSMC installer’ on Mint
You want frustration, try installing Windows 10 updates and drivers on a new laptop with a sh!tty internet connection for your neighbours
It seems you noticed my frustration.
Thanks for the quick replies and sorry about the frustrated tone. I think there is a duplicate issue on this on the forum:
I dont have any external card readers (?).
When it comes to windows 10, I try to avoid it at all cost!
