The downgrade option is becoming more and more popular in the computer world. Although the latest version is always the best, sometimes users prefer old versions. Versions that are more effective with your other programs or with the operating system. Ubuntu allows you to downgrade your programs, as long as these are in your repositories.
The system Ubuntu always offers you the latest version of the installed programs but it does not mean that it deletes the previous versions nor that it stops having it in its repositories, what's more, in some cases like Mozilla Firefox, we can find up to the last three versions of this browser.
Ubuntu allows us to downgrade as long as it has the package in the official repository
To downgrade in Ubuntu just install the version we want, but we have to install the exact package, it is useless to write the name of the program and that's it, we have to write everything, even the extension ".deb". To know this as well as the previous versions that we have in the repositories, we open a terminal and write the following:
sudo apt-cache showpkg "NOMBRE_DE_PROGRAMA"
It will show us a list with the packages that have the word »PROGRAM_NAME», this list will contain the old version of the program that we want. Now we have to install the package with the following command:
sudo apt-get install "NOMBRE-COMPLETO-DEL-PAQUETE-A-INSTALAR"
After this it will ask us if we want to install it, press the «Y» or «S» key and the downgrade process will continue. A process that does not have much difficulty or problems for any user. You can now check when opening the program that the old version is running and not the most current version. It is simple but remember that a new version is always released for something (errors, new functions, etc ...) and that will no longer be available when downgrading. Remember it because it is important and something to keep in mind.
