我尝试按照以下说明安装 Java：
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
但是在 sudo add-apt-repository ppa:webupd8team/java 之后我收到错误：
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 11, in <module>
from softwareproperties.SoftwareProperties import SoftwareProperties, shortcut_handler
ModuleNotFoundError: No module named 'softwareproperties'
我已经检查过“ls -l /usr/bin/python*”：

有人遇到过这样的问题吗？
答案1
您是否安装了软件属性？
尝试：
apt-get install -y python-software-properties software-properties-common software-properties-gtk python3-software-properties software-properties-kde
