我正在嘗試使用命令從 16 LTS 升級
sudo do-release-upgrade
但它失敗了
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'.
她想要什麼，如何滿足她？我嘗試刪除所有軟體包，launchpad.net但沒有幫助。

參考您的評論ppa:dhor/myway
以下命令列可用於刪除 PPA（此選項-r導致刪除），
sudo add-apt-repository -r ppa:dhor/myway
sudo apt-get update
您的評論關於.../webupd8team/java/ubuntu xenial main
deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main
對應（可以刪除）
sudo add-apt-repository -r ppa:webupd8team/java
sudo apt-get update
請注意該 PPA 已停止。
