If my business is going to survive after lockdown I'm going to need a serious tech upgrade. My servers are old & creaking. My previous goto #SMEServer, previously eSmith, hasn't had an upgrade since 2017. Came across #Zentyal, looks good but looks proprietary. Does anyone know of anything else that provides domain accounts, file sharing and an email server? Or how easy is it to set up all this stuff on #Ubuntu 20.04 server? I'm happy with the command line just not sure what packages I need.
