python-software-properties的安裝問題

我需要安裝最新版本的 node.js，但我的系統在儲存庫中有舊版本。我需要添加新的 ppa 源。我跟著這個教程

問題- 當我安裝“python-software-properties”包時：

sudo apt-get install python-software-properties

未安裝程序“add-apt-repository”（也未安裝 apt-add-repository）：

root@vm7590:~# add-apt-repository
The program 'add-apt-repository' is currently not installed.  You can install it by typing:
apt-get install python-software-properties

和

root@vm7590:~# apt-add-repository
The program 'apt-add-repository' is currently not installed.  You can install it by typing:
apt-get install python-software-properties

但程序“python-software-properties”已經安裝。

root@vm7590:~# sudo apt-get install python-software-properties
sudo: unable to resolve host vm7590

**我究竟做錯了什麼？**是否有其他方法可以添加 ppa 源？

我的系統如下：

root@vm7590:~# uname -a
Linux vm7590 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

您需要安裝software-properties-common而不是python-software-properties. 請參閱https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/439566。

儲存庫中的包名稱從 更改python-software-properties為python3-software-properties。安裝它，一切都會好起來的！
