Description of my issue
Hello,
I have freshly installed Younohost on a Raspberry Pi 4. On the Post installation process there was a Message that a Script could not executed correctly, I believe it was something like 34_mysql… but at the End there was a message that post installation was completed.
I then rebooted my Rpi and looked again on the Webinterface. In the Services Menu is shown that the mysql service is not running and I cannot start the service due to an Error.
I looked in the Forum for similar Errors but didnt find a clue.
Can someone here please help me with this problem?
Thank You!
