(Ubuntu 19.0.4) How to install software or upgrade from an old unsupported release? 作者: lovingyu_er 时间: 2020-12-09 09:59:00 分类: Ubuntu Good Question : My Ubuntu 's Version is :Ubuntu 19.04 TLS The repositories for older releases that are not supported (like 11.04, 11.10 and 13.04) get moved to an archive server. There are repositories available at ```http://old-releases.ubuntu.com.``` The reason for this is that it is now out of support and no longer receiving updates and security patches. <!--more--> I would urge you to consider a supported distribution. If your computer is too old in terms of memory or processor then you should consider a distribution such as Lubuntu or Xubuntu. If you want to continue using an outdated release then edit /etc/apt/sources.list and change archive.ubuntu.com and security.ubuntu.com to old-releases.ubuntu.com. You can do this with sed: ``` sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list ``` Then : ``` sudo apt-get update && sudo apt-get dist-upgrade ``` Sometimes, it might be faster to create backups of your system and reinstall using supported release instead. If you want to upgrade to Ubuntu 20 or other， try it ： ``` sudo apt-get update sudo apt-get install ubuntu-release-upgrader-core sudo do-release-upgrade ``` Document : ``` https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release ``` 标签: none
