Problems and Solutions when installing the rpm package in ubuntu

I want to install jdk on Ubuntu, because apt-get is used to install jre, and sometimes it is not easy to use. However, the rpm installation file downloaded from the Internet cannot be installed on Ubuntu, which means Ubuntu is based on Debian and can only install deb files. I searched the internet and found that AlienPackageConverter can convert files such as Jiang rpm and deb to solve this problem. Sudoapt-getinstallaliensudo wants to install jdk on Ubuntu, because it is difficult to use apt-get to install jre. However, the rpm installation file downloaded from the Internet cannot be installed on Ubuntu, which means Ubuntu is based on Debian and can only install deb files. I searched the internet and found that Alien Package Converter can convert files such as Jiang rpm and deb to solve this problem.

Sudo apt-get install alien
Sudo alien XXX. rpm
Sudo dpkg-I XXX. rpm

However, it seems that alien will make the dependency between software messy, so the best way is to try to use the software on the Ubuntu source or find the deb format Installation File.

Another method:

Apt-get install rpm
