Hello everyone,

I have done a system upgrade from the old Kernel to the old 4.14 Kernel to the 4.19 Kernel via apt upgrade.

I did experience some regressions and things not working any more.
As I'm not sure whether it's because of the upgrade process or it's a bug in the new Kernel/OS I would like to test it with a fresh install.
However the source where I previously downloaded the OS from does not work any more because of an SSL error: https://packages.pyra-handheld.com/images/stretch/

My question is, where can I download the latest OS version?

In case you are interested in the issues I have right now:
1. apt update is not working any more
    Error: Unable to parse package file /var/lib/apt/extended_state (1)
2. I can not shut down the system any more during the UI.
    When I select "Shut down" the message "A program is still running - MATE settings Daemon" appears. I can not "Shut down Anyway" or kill that program.
3. The shoulder buttons are not working as before.
    - The Fn (upper left shoulder button) does not work as Fn on the Keyboard any more
    - The combination Lower left shoulder button + Brightkey does not have any effect any more. Shift on Keyboard + Brightkey does. Before both keys did work when setting SHIFT+Brightkey as an action.

Best Wishes
Nino
