How to install RMP package in Ubuntu

The Ubuntu package format is Deb. If you want to install the RPM package, use alien to convert the RPM to Deb.
Sudo apt-Get install alien # alien is not installed by default, so install it first. If this package cannot be found, check your/etc/APT/sources. List
And add the following content:
Deb http://ubuntu.cn99.com/ubuntu/ feisty main restricted universe multiverse
Deb http://ubuntu.cn99.com/ubuntu/ feisty-security main restricted universe multiverse
Deb http://ubuntu.cn99.com/ubuntu/ feisty-Updates main restricted universe multiverse
Deb http://ubuntu.cn99.com/ubuntu/ feisty-proposed main restricted universe multiverse
Deb http://ubuntu.cn99.com/ubuntu/ feisty-backports main restricted universe multiverse

Sudo alien XXXX. RPM # convert RPM to Deb. a xxxx. Deb with the same name is generated.
Sudo dpkg-I XXXX. Deb # Installation
Note that the Deb package converted from alien cannot be installed smoothly in 100%, so it is best to use Deb directly if you can find Deb.
Sometimes, the software we want to use is not included in the Ubuntu repository, and the program itself does not provide the Deb package that can be used by Ubuntu, and you do not want to compile it from the source code. But if the software provides an RPM package, we can also install it in Ubuntu.
Method 1:
1. Install the alien and fakeroot tools first. The former can convert the RPM package to the Deb package. The installation command is:
Sudo apt-Get install alien fakeroot
2. Download the RPM package that needs to be installed for backup, for example, package. rpm.
3. Use alien to convert an RPM package to a deb package:
Fakeroot alien package. rpm
4. Once the conversion is successful, we can immediately use the following command to install it:
Sudo dpkg-I package. Deb
Method 2:
1. Code:
Sudo apt-Get install RPM alien
2. Code:
Alien-D package. rpm
3. Code:
Sudo dpkg-I package. Deb
