in Ubuntu, the software is installed in a Deb file, and some Linux-ready software is a file in other formats, such as ". RPM" format, which cannot be installed directly in Ubuntu and requires a format conversion. The following examples illustrate the specific operation of format conversion. 1, first install the Format conversion tool. In the terminal input "sudo apt-get install Alien", press the terminal prompt operation can complete the conversion tool installation. 2. After the conversion tool is installed, it can be converted into a format. For example I want to install "opera-stable_45.0.2552.635_amd64.rpm":sudo alien--script opera-stable_45.0.2552.635_amd64.rpm
after entering the screen it appears that you want to enter the ID, as prompted to enter after the format conversion. 3. After the conversion is complete, you can find the converted ". Deb" package in the home folder, then you can install the sudo dpkg-i opera-stable_45.0.2552.635_amd64. Deb
