Cyrus the Great's questions

我正在尝试在 Ubuntu 18.4 上安装 QGIS，所以我添加了这个 repo：

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update

最后更新了我的资源并安装了 QGis：

sudo apt update
sudo apt install qgis

但是在运行应用程序时出现以下错误：

groot@groot-Product:~$ qgis

退出应用程序后，出现以下错误：

我正在尝试在 Ubuntu 18.04 LTS 上安装 Oracle Java 8。

$ java --version

Command 'java' not found, but can be installed with:

sudo apt install default-jre            
sudo apt install openjdk-11-jre-headless
sudo apt install openjdk-8-jre-headless  

根据教程我添加了ppa：

sudo add-apt-repository ppa:webupd8team/java

之后我更新了我的操作系统：

$ sudo torsocks apt-get update
Hit:1 http://ppa.launchpad.net/webupd8team/java/ubuntu bionic InRelease        
Ign:2 http://dl.google.com/linux/chrome/deb stable InRelease                   
Hit:3 http://us.archive.ubuntu.com/ubuntu bionic InRelease               
Hit:4 http://dl.google.com/linux/chrome/deb stable Release              
Hit:6 http://us.archive.ubuntu.com/ubuntu bionic-updates InRelease      
Hit:7 http://us.archive.ubuntu.com/ubuntu bionic-backports InRelease
Hit:8 http://us.archive.ubuntu.com/ubuntu bionic-security InRelease
Reading package lists... Done

然后我跑了：

sudo apt-get install oracle-java8-installer

但我得到了：

$ sudo torsocks apt-get install oracle-java8-installer
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package oracle-java8-installer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'oracle-java8-installer' has no installation candidate

我找到了这个解决方案，但它不起作用，我得到了同样的错误
