I made the switch! Well mostly, my main PC that I use for work (audio, music, etc) is still Windows for now while I figure out if I can do what I need with Linux. 3 days ago I threw Mint on my old laptop (which I don’t use much for testing as it’s still slow, even with Linux) and wanted to use my main laptop to test for switching my PC. Unfortunately it’s a Samsung Galaxy Book3 Ultra, which apparently has issues with Linux hardware-wise. I got everything up and running (except for the webcam which was expected) and found Ubuntu Studio, which seems to basically be Ubuntu with auto-install of a suite of audio and video programs, and a low latency kernel (whatever that means. I’ll get there to figure it out eventually).
I’ve learned a LOT. Pulling in Windows vst files through Wine and yabridge was a journey. Every time I fixed an issue and took a step forward, I encountered a new one haha. But, I got it working. I LOVED figuring out the problems, even if I wanted to pull my hair out. The terminal is…really neat.
Anyway it’s important to me to try and learn the how/why as I go so here’s my question. Librewolf. It installs via terminal, and I’m having issues on Ubuntu Studio. I tried it on Mint and it installed fine. Ubuntu studio however throws up this error: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F
I tried sudo apt-get install -f (which I think looks for missing dependencies and stuff?) but no go. Since both distros are Debian, I’m guessing the biggest difference between Mint and Ubuntu Studio is the kernel? I’ve been able to fix things with missing dependencies but I’m guessing the public key is something different?
ELI5, why does it work on Mint and not Ubuntu Studio?
Edit: Got it thanks to u/frongt I added the key and it’s all good!
Execute the following commands in terminal
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <PUBKEY>
where <PUBKEY> is your missing public key for repository, e.g. 8BAF9A6F.
Then update
sudo apt-get update
Woof, hard flashback to my first steps on Linux. Idk, these problems leave, when you try to buy better supported Linux hardware. Thinkpads and XPS (second hand / refurbed) are near 100% supported (maybe some have a quirky nvidia gpu which needs some extra steps) and really cheap these days. I would sell stupid Samsung / Chromebook stuff and buy Dell/Lenovo for less headache.
Haha yeah I got the Samsung 50% off about a month before I started taking leaving big tech seriously. Honestly, I really like that there are issues, workarounds, and it generally doesn’t play nice. I learn best by doing and I’ve already learned a tonne just by having to run terminal commands to get things going, even things like touchpad issues, audio, power light staying on, etc. My next computer I’ll focus on Linux hardware priorities (I think AMD plays well) but for now, fixing is how I’m learning.
