Ubuntu 从 17.04 升级到 18.04

Question

我已经安装了 ubuntu 17.04，我想将它升级到 18.04。当我尝试这样做时：

 sudo do-release-upgrade

我收到一条消息说An upgrade from 'zesty' to 'bionic' is not supported with this tool。需要输入才能继续进行。

sudo do-release-upgrade

Answer 1

这在任何地方都没有得到正确解释，这是您需要做的（或我是如何做的）：

升级到 17.04 到 17.10： 无法从 ubuntu 17.04 升级到 17.10

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak #to be safe
sudo sed -i -re 's/old-releases.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list
sudo sed -i -re 's/zesty/artful/g' /etc/apt/sources.list
sudo apt update
sudo apt dist-upgrade
sudo apt autoremove

（链接说使用 aptitude 而不是 apt-get）

从 17.10 升级到 18.04：EOLUpgrades

将 /etc/apt/sources.list 中的所有内容替换为：

## EOL upgrade sources.list
# Required
deb http://old-releases.ubuntu.com/ubuntu/ artful main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ artful-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ artful-security main restricted universe multiverse

# Optional
#deb http://old-releases.ubuntu.com/ubuntu/ artful-backports main restricted universe multiverse

然后运行升级：

apt-get update
apt-get dist-upgrade
do-release-upgrade

当被问到时，按照它说的做，然后等待它完成，你就应该完成了。

据WiMantis 称，sudo sed -i -re 's/old-releases.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list不再需要。WiMantis发表了一篇关于它的帖子。相关部分：

# Upgrade from 17.04 to 17.10

# backup current sources file (just in case)
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

# change version codename from 'zesty' to 'artful'
sudo sed -i -re 's/zesty/artful/g' /etc/apt/sources.list

# 17.10 has reached it's end of life
# so we fetch from 'old-releases.ubuntu.com'
sudo sed -i -re 's/archive.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

sudo apt update
sudo apt dist-upgrade
sudo apt autoremove

 

# Upgrade from 17.10 to 18.04 LTS

# change version codename from 'artful' to 'bionic'
sudo sed -i -re 's/artful/bionic/g' /etc/apt/sources.list

# 18.04 has NOT reached it's end of life yet (due in 2028)
# so we fetch from 'archive.ubuntu.com'
sudo sed -i -re 's/old-releases.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list

sudo apt update
sudo apt dist-upgrade
sudo apt autoremove
