1)用yum源安装dos2unix报错

[home@localhost ~]$ sudo yum -y install dos2unix

Loaded plugins: fastestmirror
file:///mnt/repodata/repomd.xml: [Errno 14] curl#37 - "Couldn't open file /mnt/repodata/repomd.xml"
Trying other mirror.
Loading mirror speeds from cached hostfile
Package matching dos2unix-6.0.3-4.el7.x86_64 already installed. Checking for update.
Nothing to do

2）改用rpm包直接安装，先到 http://rpm.pbone.net/ 下载dos2unix的安装包dos2unix-7.3.4-1.mga6.x86_64.rpm

[home@localhost temp]$ sudo rpm -ivh dos2unix-7.3.4-1.mga6.x86_64.rpm
[sudo] password for home:
warning: dos2unix-7.3.4-1.mga6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID 80420f66: NOKEY
