> Maintenance updates will be provided for 5 years until April 2027 386 for Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud, and Ubuntu Core. All the remaining flavours will be supported for 3 years. Additional security support is available with ESM (Extended Security Maintenance).
The graphic (from the official website)[1] is slightly misleading because it doesn't differentiate between "Hardware & Maintenance Updates" and "Maintenance Updates". The source for these [2] marks these as 2 separate dates. The undocumented policy seems to be "hardware+Maintenance updates for 2 years", and "maintenance updates for another 3". Ubuntu doesn't seem to document what's the difference between these.
I'd reported this to Ubuntu a few years ago[3], but it wasn't deemed confusing. It's not helpful that Ubuntu website changed the definition of EOL from "end-of-unpaid-LTS-support to end of ESM. in the wiki[4] to make it appear like older releases are still supported.
