I film myself locking the door. I have evidence.

The important question is if the UEFI shell can run Doom.

It's also worth mentioning that the snap system is quite disliked by a lot of users for various reasons, like stuff not working right.

I suppose this article is a good example of snaps not working right.

There's software to check how many mAh most laptop batteres are able to take up and deliver, compared to what they shipped with. Modern ones even have how many complete 0-100 charge cycluses the battery have gone through. You can check if you think there's something dodgy about the battery. I've actually seen laptops factory shipped with smaller batteries than ordered.

But knowing linux and seeing you had an issue with the power profiles I'd think it's software related hah. Is there a discrete GPU onboard it's using instead of the power-saving one perhpas?. Also, did you turn off that awful "dynamic background" on youtube that continually taxes the CPU?

Lizards were created by boomer turtle parents selling the family turtle shells to spend the rest of their lives on a cruise ship.

Happy to help, sorry I can't offer a simpler solution that avoids reformatting. It's probably doable if you want to do more fine grain troubleshooting but I've never found it to be worth the time.

For my home self-hosting I also prefer pre-made scripts exactly to avoid having to manually set up everything. It's such a slog and particularly if I have to restart from scratch. What's the goal of your project, perhaps something like Yunohost or even DietPi could save you a lot of work and get straight to the fun of self-hosting?

Wait, are you a schubadiver as well?

Something is completely shutting your server off from the internet, despite it having full LAN access. The only time I've run into this exact issue was when I misconfigured the firewall on a server, effectively only allowing for local connections. I simply started over by reinstalling Debian, wiping all my mistakes. But it could also be a setting on your router, and without you knowing what changes you made it's hard to give any reasonable advice.

These are just shots in the dark, and other might offer better solutions but I'd try;

1. Boot the laptop into a live session directly from USB. All settings are default. Test again, either wget or maybe ping a website. If it works, it's the server setup and I'd start over. If not...

2. Try reversing all changes on the router, give the server a different static IP.

3. Back up the router configuration to a file, consider making notes of important changes, reset the router and try again. If it STILL doesn't work you can restore the important settings. If it works, you can reimplement the settings from your notes. (unless we're talking manually imported VPN certificates and similar lol)

Sorry I wasn't able to help you out, I'm hosting from home and it's a fantastic thing when things

I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works

Haha yes, as mentioned. The issue is a setting on your laptop server installation. The simplest thing is just reinstalling and starting over.

Here I've tried wget https://104.18.114.97. It's able to connect to the IP on port 443, but shows an error message since I'm not using a domain name. But at least I know I've reached the server.

Please try wget https://104.18.114.97, if this one goes through I'd think the problem could be related to a faulty forwarding of regular internet traffic (port 80). If that fails as well I'd guess it's to due with the DHCP/Static IP's and involves your router. I'm absolutely clueless about Vodafone routers though.

Edit: Any connection would show "The certificate's owner does not match hostname ‘104.18.114.97’"

Yeah, I realized after the fact. This should work: wget 104.18.114.97, and you should get a ERROR 403: Forbidden if your server has any internet connection.

I bet it has something to do with the LAN DHCP setup, since you have to set a static IP for the server...

Update - That won't work at all if it is indeed the issue. Let me think for a sec on how to pull external ip by doing a IP wget...
