News, Reviews & Betas which includes large community peer support Canonical will be ending updates for Ubuntu 21.04 on January 20. This gives you a week to upgrade your systems to Ubuntu 21.10 before they become unsafe to use and vulnerable to malware.
It’s January 13 which means there’s just one week left until Canonical stops giving out updates for Ubuntu 21.04 ‘Hirsute Hippo’ which launched last April. As it’s an inter-LTS release, it only receives 9-months of updates, and then it’s time to move on. The best plan for people still running Ubuntu 21.04 is to upgrade to Ubuntu 21.10 and then to upgrade to Ubuntu 22.04 LTS (not available until April) before July 14.
