Text in the last paragraph at this web link seems to limit flavour support: "Maintenance updates are provided for 5 years for Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud, Ubuntu Base, and Ubuntu Kylin. All the remaining flavours are supported for 3 years." Has Lubuntu 16.04 LTS reached End of Public Support & is unsupported as suggested in comments at Lubuntu in PowerPC ?
Lubuntu 16.04 LTS (Xenial Xerus) Released! (from the confirmed official Lubuntu web site) says "Lubuntu 16.04 LTS will be supported until April 2019, with three years of support." That pretty much settles it; it has reached EoPS (End of Public Support). Fortunately, they have published Lubuntu 18.04 LTS in 32-bit and 64-bit editions.
