From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I recently installed chromium, created a new user and logged into a website. After my work was done, I removed chromium with "sudo dnf remove chromium".

A few days later I installed chromium again through dnf. My user account was still there and I was logged into the same site.

Is there a way to avoid this and uninstall an app along with all its user data?

Thanks. I wish there was a more straightforward process though.

Every other OS I've used purges all app data after uninstalling, why is Linux different?

If you install something as a Flatpak, you have that option.

And Windows absolutely does not remove everything after an app is uninstalled.

Chrome definitely leaves permanent traces on windows when you uninstall it

And on MacOS there isn't an uninstaller too, you just send the app to the trash, but all the preferences and leftovers keep littering the drive

One of the reason is that apps can place their files in any place they want so the app manager is not aware of those locations.

Even if it would know then the user still would need a way to remove the app without deleting data, imagine installing Developer IDE or chat app and uninstall process would remove your chats or projects. Imagine app dev accidentally set the "directory that store app data" to /home, it would be bad.

I not once uninstalled app to install different (for example older) version due to bugs in new one.

Having the logic allowing to optionally delete data would introduce additional complexity so most old package managers never introduced that feature.

But I agree that we should slowly introduce a way to to that. Some app managers that manage flatpaks now allow to delete user data after uninstalling app, this now could be done universally because apps installed using flatpak store their data in their own separated/dedicated directory that flatpak engine know about so (unless you give permissions to access other location) thw manager know where the app store data so can offer easy way to remove it.

I think (?) it's generally true that the root user should never mess with users' files.

Imagine your home directory is shared across many systems on a network (my alma mater did this). It would be really bad if a sysadmin for alpha.university.edu removed a program, and suddenly your personal settings were removed from beta.university.edu


even though that computer still has the program.

This is one of the "UNIX on the desktop" issues


a lot is designed for a sysadmin/multiuser situation, and it has some gotchas when using it as a desktop machine (I'm used to/really appreciate the directory structure and settings management at this point, but it may take some getting used to).
