Ubuntu Font (there is a download link at the bottom of the page). Source: about 2 years ago

Download it from https://design.ubuntu.com/font/, extract the archive, drop the folder into ~/.local/share/fonts/ (or /usr/local/share/fonts/ for it to be available system-wide), run fc-cache for good measure, done. Source: about 2 years ago

It took me years to switch from Ubuntu Mono[1] to IBM Plex Mono[2] but now I feel like I'm never gonna change fonts again. I gave Cascadia a try but it feels way too bold. On paper it looks like a really cool project but after I've installed it it felt like all my code was shouting at me (I mean even more than usual), it was disturbing.

The font in the second panel is mononoki. Source: about 2 years ago

Mononoki is my recent favorite (unmentioned yet, but surely popular). https://madmalik.github.io/mononoki/ Monofur is a wild font I'm mildly surprised was omitted. I did use it full-time for a while maybe 10 years ago, but it's maybe not the best daily driver. https://www.fontspace.com/monofur-font-f39937. - Source: Hacker News / almost 3 years ago

Mononoki is my latest find and it's awesome. Source: almost 3 years ago

Use of ANY system font (I like mononoki for example). Source: over 3 years ago

Here you go. Its probably the open-source font with the best chance of being standardized(apart from Jetbrains mono). Source: over 3 years ago
