ubuntu 14上装calibre出现的问题

＊＊＊＊@ubuntu:~/SPAD/IC61$ calibre
ERROR: Unknown Linux operating system environment.
可以找到calibre，但是运行时报error，不知道如何解决

calibre 只认RHEL

要不你就骗骗calibre，假装这个是RHEL

but how to fool it?
I'm trying to install calibre on ubuntu 16.04
Thank you very much！

Create file named redhat-release under /etc with contentCentOS Linux release 7.3.1611 (Core)

GOOD MATEIRAL
