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 have been using various Debian-flavored Linux variets for several years in both desktop and server.
Recently I got a System76 laptop for work because they are food quality, repairable, and mostly "just work". The main issue I have run into is Cisco Secure Client (formerly AnyConnect) simply breaks in Ubuntu/PoP. If I do get it to install by ignoring Cisco's shitty instructions, it either won't route traffic once connected or corrupt itself attempting to auto-update.
It is purely a Cisco issue because they don't put much effort into their Linux VPN software. Other VPNs not only work easily, but can also integrate into PoP Cosmic. Cisco and their restrictive nature just make the process impossible.
Heck, you can't even download their VPN software without a Cisco contract. So if my company doesn't provide the correct version or distro package, there is no way for me to get it. Since most people on the helpdesk don't know anything about Linux, they simply provide the generic Linux.tar.gz file instead of the DEB or RPM files.
I gave up and installed Windows on a second NVMe.
