Converting rpm into deb, tgz and vice versa using alien

To convert rpm to deb, or vice versa, we can use a tool called alien. To install alien in an ubuntu machine:

$ sudo apt install alien -y

To install alien in redhat based distro:

$ sudo dnf install alien -y

Once installed, we can easily convert any rpm into deb:

$ sudo alien --to-deb myapp.rpm

A file called myapp.deb will be created once alien finished doing its magic.

We can also use alien to convert deb to rpm:

$ sudo alien --to-rpm myapp.deb

A file called myapp.rpm will be created.

We can also convert to tgz package:

$ sudo alien --to-tgz myapp.deb

To generate multiple packages format:

$ sudo alien --to-rpm --to-deb myapp.tgz
