Linux Mint 17.1 無法添加 PPA - Linux

apt-add-repository 指令無法使用

會遇到以下訊息：

Traceback (most recent call last):
File "/usr/bin/apt-add-repository", line 91, in <module>
sp = SoftwareProperties(options=options)
File
"/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py",
line 109, in __init__
self.reload_sourceslist()
File
"/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py",
line 599, in reload_sourceslist
self.distro.get_sources(self.sourceslist)

get_sources
(self.id, self.codename))
aptsources.distro.NoDistroTemplateException: Error: could not find a
distribution template for LinuxMint/rebecca

想詢問除了手動加入 Ubuntu PPA 外，還有沒有什麼其他解決辦法。感謝。
