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.

System partitions encryption (lemmy.ml)

Are the Linux system partitions encrypted by default ?, I've tried to encrypt them using Veracrypt, but it says that it only works on Windows ?.

PopOS had optional disk encryption when you install it, not sure about other distros though

No. They are not encrypted by default on all distros that I am aware of.

Debian allows setting up disk encryption during install for example. Never heard of VeraCrypt, I don't think that's popular on Linux. The relevant under the hood parts if you're interested in how it works on Linux are:

dm-crypt: Linux kernel feature for accessing encrypted partitions
Luks: A header format / standard for encrypted partitions
cryptsetup: command line tool to set up and manage all this

you must've downloaded the wrong VeraCrypt pogram. Download one for your Linux system after deleting the one you have now.

No, VeraCrypt only offers full-disk encryption on Windows

VeraCrypt can encrypt entire disks on Linux but, as far as I've seen, nobody has done the work to make Linux boot from a VeraCrypt volume. In theory it should be possible the same as it is with LUKS, though - someone would just need to write the scripts to build an initrd that decrypts a veracrypt partition and calls pivot_root.
