Sivun hurstinapu.fi head:istä löytyy tuo robots meta tägi (<meta name="robots" content="noindex, nofollow">), eli lienee syy että ainakin pääsivu ei hakukoneissa näy. Tarkistin pari alasivua mutta en kaikkia, ja niissä tuo tägi oli myös.
Ihmettelen vaan että miksi se on sinne laitettu, en osaa hyvää syytä sille sanoa tässä tapauksessa. Admin-sivujen jne. kohdalla ymmärrän, mutta luulisi että he haluavat että nuo webbisivut kuitenkin hakukoneista löytyvät.
Quick tip for the author and those reading, instead of doing as in the article noted e.g. sudo nano or the like, you can use sudoedit (or sudo -e). The advantage of this is that it will use whatever you have configured as an editor (through $SUDO_EDITOR, $VISUAL or $EDITOR), and will use your configuration files while editing instead of root's, meaning if you have a sick custom neovim or emacs setup you don't have to keep those settings files in sync with the root account. ;)
As the unfortunate owner of a same-gen MBP with the same wireless card, you're looking at using the proprietary driver (I at least never had any luck with the open-source ones). Luckily, Debian do support those, and even have wiki page for them: https://wiki.debian.org/wl
Does require some extra configuration though. If you happen to have a Android phone, you should be able to use that for USB-tethering to have internet access on the device you're installing on, will make the process a lot easier (you don't even need a SIM in it, you can tether your wifi, that's what I ended up doing 😅).
There's a Floatplan exclusive from two months ago, and I think another one from a little further back. As for the other comments about her leaving LTT, I've heard those rumours as well but never managed to find any source for them, so not sure.
