I hope I did not choose the wrong snap or tag.
I have installed omv on my pi 8GB version and after that, I proceed to install docker and activate portainer. Docker was installed on external storage. I installed ncp and everything was running perfectly. I restarted my pi and after that, I got the error:
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)
My external source was mounted before.
ncp-report is throwing this errors:
Cannot load Zend OPcache - it was already loaded
An unhandled exception has been thrown:
