使用lsb_release 查看ubuntu版本号时报错：ValueError: could not convert string to float: '8.04 LTS’
$ sudo lsb_release -a

原因：lsb_release.py这个东西貌似有问题。从conda的报错信息里面也能看出来。
解决：
$ sudo vi /usr/share/pyshared/lsb_release.py
把 48 行
从
RELEASES_ORDER.sort(key=lambda n: float(n[0]))
改成
RELEASES_ORDER.sort(key=lambda n: float(n[0].split()[0]))
然后lsb_release可以用了，conda也可以用了
$ lsb_release -a
