很早之前在ubuntu安装软件时遇到的问题,今天打开ubuntu看到了,总结如下:
在ubuntu中我们使用sudo apt-get install 或者dpkg -i *.deb安装软件常常提示“有未能满足的依赖关系“,这是因为当前软件源中依赖库的版本不满足软件的要求。
解决办法:
步骤1:更新软件源。ubuntu自带的软件源比较旧,很多的软件版本较低,国内比较好用的源有阿里源;
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak #备份
sudo vim /etc/apt/sources.list #修改源列表,将阿里云源复制到sources.list文件中
sudo apt-get update #更新本地源列表;
阿里云源:
deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
步骤2:sudo apt-get install 软件名称。这里会提示“有未能满足的依赖关系“。
步骤3:sudo apt-get -f install。这个命令会针对当前不满足的依赖关系,下载正确版本的依赖库。
步骤4:sudo apt-get install 软件名称。这一步就会正确安装软件了。
