Ubuntu 16.04 至 18.04 升级失败

我正在尝试从 16.04 升级到 18.04。输出结果sudo do-release-upgrade如下：

 ubuntu-desktop
Exception during pm.DoInstall():  E:Sub-process /usr/bin/dpkg returned an error code (1)

Could not install the upgrades 

The upgrade has aborted. Your system could be in an unusable state. A 
recovery will run now (dpkg --configure -a). 

dpkg: dependency problems prevent configuration of ubuntu-desktop:

Upgrade complete 

The upgrade has completed but there were errors during the upgrade 
process. 

To continue please press [ENTER]

的输出为sudo apt update：

并sudo dpkg --configure -a给出：

  Package gdm3 is not installed.
 ubuntu-desktop depends on gnome-shell; however:
  Package gnome-shell is not installed.

最后，输出apt-cache policy：

Package files:

     origin archive.ubuntu.com
Pinned packages:
E: No priority (or zero) specified for pin

我还没有重启电脑。如何确保一切（或至少是包管理）正常运行？

答案1

要删除“ E: No priority (or zero) specified for pin”消息，您必须通过以下方式删除 Ubuntu Advantage (UA) ESM 文件：

sudo rm /etc/apt/preferences.d/ubuntu-esm-infra
sudo rm /etc/apt/sources.list.d/ubuntu-esm-infra.list

因为 Ubuntu 18.04 LTS 是受支持的版本，所以这里实际上不需要 UA ESM。

然后检查 中的行是否正确/etc/apt/sources.list。将行更改为包含以下内容：

deb http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-backports main restricted universe multiverse

sudo apt-get update然后再次运行：

sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get upgrade # rerun upgrade
sudo apt-get dist-upgrade # install newest dependencies

最后删除 UA

sudo apt-get purge ubuntu-advantage-tools --autoremove
