由于缺少 phpMyAdmin PPA，无法将 Ubuntu 服务器 16.04 更新至 18.04

我正在尝试安装 16.04 的最新更新，以便升级到 18.04。我遇到了 phpMyAdmin PPA 错误，我理解这是由于原软件包维护者（nijel）已删除 PPA。

因此我尝试删除 PPA：

sudo add-apt-repository --remove ppa:nijel/phpmyadmin

但这不起作用：

Cannot add PPA: 'ppa:~nijel/ubuntu/phpmyadmin'.
The user named '~nijel' has no PPA named 'ubuntu/phpmyadmin'
Please choose from the following available PPAs:

我也尝试过这个：

sudo add-apt-repository universe
'universe' distribution component is already enabled for all sources.
sudo apt install phpmyadmin

但我明白：

Reading package lists... Done
Building dependency tree
Reading state information... Done
phpmyadmin is already the newest version (4:4.6.6-1+deb.cihar.com~xenial.2).

我该如何解决这个问题以便可以升级到 18.04？

答案1

你必须通过以下方式从系统中删除 PPA

sudo mv /etc/apt/sources.list.d/*nijel*.list ~/
sudo add-apt-repository -r ppa:phpmyadmin/ppa

然后将phpmyadmin包还原为来自官方存储库的版本：

sudo apt-get install --reinstall phpmyadmin=4:4.5.4.1-2ubuntu2.1

然后运行sudo apt-get update以确保错误消失并再次运行sudo do-release-upgrade。
