Unattended Upgrades only checks and updates programs in repos it knows about. As you found out, you’ll need to add the custom repository to the Origins pattern in 50unattended-upgrades.

You can find a list of all repositories and their data using apt policy

Here are the custom repositories I have on one of my servers:

 500 https://repo.zabbix.com/zabbix/7.0/debian bookworm/main all Packages
     release v=12,o=Zabbix,a=zabbix,n=bookworm,l=zabbix,c=main,b=all
     origin repo.zabbix.com
 500 https://repo.zabbix.com/zabbix/7.0/debian bookworm/main amd64 Packages
     release v=12,o=Zabbix,a=zabbix,n=bookworm,l=zabbix,c=main,b=amd64
     origin repo.zabbix.com
 500 https://pkgs.tailscale.com/stable/debian bookworm/main all Packages
     release o=Tailscale,n=bookworm,l=Tailscale,c=main,b=all
     origin pkgs.tailscale.com
 500 https://pkgs.tailscale.com/stable/debian bookworm/main amd64 Packages
     release o=Tailscale,n=bookworm,l=Tailscale,c=main,b=amd64
     origin pkgs.tailscale.com
 500 https://deb.nodesource.com/node_20.x nodistro/main amd64 Packages
     release o=. nodistro,a=nodistro,n=nodistro,l=. nodistro,c=main,b=amd64
     origin deb.nodesource.com

Look at the line starting with release and search for a combination that uniquely identifies the Caddy repository.
The output above is using the short form keywords, while the examples in 50unattended-upgrades use the long form. It’s fine to use either.
One special case is the site keyword. This is the URL coming after origin in the output above and might be confusing.

Keywords

//   a,archive,suite (eg, "stable")
//   c,component     (eg, "main", "contrib", "non-free")
//   l,label         (eg, "Debian", "Debian-Security")
//   o,origin        (eg, "Debian", "Unofficial Multimedia Packages")
//   n,codename      (eg, "jessie", "jessie-updates")
//     site          (eg, "http.debian.net")

Based on the apt policy output above, here’s what I use to enable automatic updates for these repositories.
Using origin and codename follows the standard Debian repos and I’d recommend using that if possible.
Node doesn’t provide a reasonable repo file, so I had to set site based on the URL behind origin in apt policy

"site=deb.nodesource.com"; //Nodesource repository
"origin=Zabbix,codename=${distro_codename}"; //Zabbix Agent repository
"origin=Tailscale,codename=${distro_codename}"; //Tailscale repository

Switched after Louis’ video about it. Haven’t tried the voice yet, but just having swipe typing and suggestions again is a definite improvement.

Yeah, but you need root anyways to mount disks (most of the time), so doing a quick chown isn’t that much effort.

Edit: chown > chmod

I use multiple subdirectories under /mnt for my fstab/systemd-mount managed disks. That includes local and network locations.

Download more RAM

Without docker you still just copy your files from Windows to Linux, though you have to find the right directories for that. Jellyfin can be installed directly on Debian. Just add their repo and go

You can’t really install packages or modify configs on the host without root. Containers can only do some parts.

Maybe, but now I still need to remember the alias or distribute it to any machine I’m working on.
Not that difficult if you have everything managed with Ansible or similar anyways, but lots of people likely don’t have that setup.

As someone who speaks a language with gendered pronouns but no neutral option, this is very awkward to deal with.

Never used Shopify unfortunately, so I can’t help you with that.

The way I tag media is using MediaElch. It requires manually going through each series and identifying it, but with your proper naming it should give decent suggestions already.
If some metadata is missing for single episodes, try changing the metadata provider, sometimes one or the other just has bad/incomplete data.

As someone who writes bash scripts, fuck no, this is a terrible language and it shouldn’t be used for anything more complex than sticking two programs together.

Also, parallelism goes right out of the window.

Maybe you’d convince me with a real programming language.

I might try run0 for fun, but I don’t think it’ll replace sudo any time soon.
The biggest issue I see is run0 purposely not copying any environment variables except for TERM.
You’d have to specify which editor to use, the current directory, stuff like PATH and HOME every time you run a command.

I think hate is really too strong of a word, dislike at most for me.
My biggest issue with Microsoft is a lack of trust. Apart from that, I just like my Linux setup more and find it easier to use.
Stuff I want to do works how I want to do it and how I’m (now) used to it.
Regardless, I use Windows at work, manage Windows Servers and Azure. It’s just how it is.

Because none of the projects you mentioned are GNU projects.

If you only need file syncing, there are better options than Nextcloud. But Nextcloud is the only real option if you want to create a full suite of replacements for office365 or google thanks to the large plugin ecosystem.

You could download stressapptest and run that memory benchmark in the normal system.

I’m not sure how well the current version of Memtest does, but when I was overclocking I was told not to use it as it couldn’t reliably get memory to crash. (Funny problem to have). The two recommended tools are Windows only, so I found stressapptest as the best alternative.

I’d never heard of Transsion before, so I took a quick look on Wikipedia.

TLDR:
They sell mostly inexpensive phones in poorer regions.
Features of their phones are targeted for those regions, like Africa, where they have special features to calibrate camera exposure for darker skin, retain dual SIM and support many local languages.

You hacked too hard

Theoretically cryptocurrencies are interesting, but Bitcoin just isn’t usable.

Bitcoin and many other currencies have way too many and large fluctuations in value for daily use.
Bitcoin specifically is not practical for transactions in general due to cost and block size limits. Yes, lightning exists, but maybe your technology is shit if it needs a second overlay network to function.
Instead of fixing those issues, most other coins are just pump and dump schemes for a quick buck.
Only very few coins try to do something different and fix some of these issues.
