我目前的git版本1.7.9.5 ...
我需要升级到至少git 1.7.10才能让git clone命令正常工作
我尝试sudo add-apt-repository ppa:git-core/ppa升级但导致了这个:
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 125, in <module>
ppa_info = get_ppa_info_from_lp(user, ppa_name)
File "/usr/lib/python2.7/dist-packages/softwareproperties/ppa.py", line 80, in get_ppa_info_from_lp
curl.perform()
pycurl.error: (7, "couldn't connect to host")
我应该做些什么来安装最新的git(进行升级)？
