如何“从 Launchpad PPA 中删除软件”以进行发布升级？

Question

我正在尝试使用命令从 16 LTS 升级

sudo do-release-upgrade

但它失败了

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

This was likely caused by:
* Unofficial software packages not provided by Ubuntu
Please use the tool 'ppa-purge' from the ppa-purge
package to remove software from a Launchpad PPA and
try the upgrade again.

If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.If
you want to investigate this yourself the log files in
'/var/log/dist-upgrade' will contain details about the upgrade.
Specifically, look at 'main.log' and 'apt.log'.

她想要什么，如何满足她？我试图从中删除所有软件包，launchpad.net但没有帮助。

参考您的评论ppa:dhor/myway

以下命令行可用于删除 PPA（该选项-r导致删除），

sudo add-apt-repository -r ppa:dhor/myway
sudo apt-get update

您的评论关于.../webupd8team/java/ubuntu xenial main

deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main

对应于（可以删除）

sudo add-apt-repository -r ppa:webupd8team/java
sudo apt-get update

请注意，该 PPA 已停止使用。
