sudo apt update && sudo apt dist-upgrade


sudo do-release-upgrade

没有直接升级路径。

  • 支持的方法是将从16.04升级到18.04，然后再从18.04升级到20.04，

    • 开始之前备份或VM快照。 
      • 
sudo apt update


sudo apt upgrade // Prepare the 16.04 system for release-upgrade


do-release-upgrade // 16.04 to 18.04. The system will prompt you for a password



sudo apt update


sudo apt upgrade // Check for errors. Stop if there are errors.


do-release-upgrade -d // The -d is required until August 13, 2020 when 20.04.1


 // is released. After that, DON'T use -d.
