Despite it being one of the most popular and feature rich download managers out there and it being foss, it seems that most repos don't have it ( except for flahub iirc) Is there is any reason behind that?
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.

And if you're distro isn't one that pushes out fast updates, then neither will work consistently.
