How to Upgrade Debian 12 to 13 in Proxmox LXC Without CREDENTIALS Errors Fix systemd credential issues and upgrade your Debian LXC containers on Proxmox 9

POV: You decide to "quickly" upgrade your Debian LXC containers to Trixie, because Reddit said it was easy.

Turns out systemd 256+ said "nah" to unprivileged containers.

Good news: There's a 5-minute fix.

How to Install Docker on Debian for GPU Passthrough and Transcoding A Practical Guide to Docker GPU Passthrough on Home Servers

Reddit: “GPU passthrough in Docker is easy!”

Reality: 3AM, permission denied on /dev/dri, Jellyfin ignoring your GPU and beating your CPU like it has an unpaid gambling debt.

Here’s the guide that actually works:

Master the Basics - SMB Guide for Media Servers Install, configure, and run SMB like you own the network (because you do).

Running NFS without root_squash? Bold. Not so smart, but bold.

Remote root stays root.

Every user maps to anonuid.

Jellyfin + Intel QuickSync in Unprivileged LXC - The Complete Guide Give Jellyfin real hardware transcoding. It is easier than you think.

Why I Ditched My VM NAS and Went Bare-Metal (And You Should Too) From Fragile VM to Bulletproof Bare-Metal NAS

Is your VM NAS a ticking time bomb?

Mine “mostly worked”… until Jellyfin in an unprivileged LXC lost half my library.

Mounts failed. Containers booted too early. Total chaos.

Why I Ditched My VM NAS and Went Bare-Metal
(and regained some of my sanity back):

🪦 RIP my old Dell PERC H310. You had a good 10 year run. Now replaced with a new to me LSI 9300-8i. I hope it gives me another 10 years or more.

My wife has said the same. I see it as another life insurance policy. I'm working on simplifying and documenting my setup so she can just hand the documents to someone and they can fix it or tear it down.

Is it still a homelab if the whole family notices when it goes down?

Feels less like tinkering, more like running a business… with impossible-to-please clients.

Congrats! You’re now CIO, CTO, sysadmin, and helpdesk. All unpaid.

And yet somehow… it’s still fun.

Two Years of LXC Hell - Why I Crawled Back to Docker (And You Should Too) How I Escaped LXC Hell and Built a Media Stack That Doesn’t Suck

I spent 2 years running the Arr suite in unprivileged LXC containers.
It was *fine* until NFS ghosts, stale handles, and permission errors drove me insane.

I rebuilt it all in Docker Compose. It finally works.
Here’s the setup I should’ve used from the start:
🔗 diymediaserver.com/post/two-yea...

Yeah, I’ve been radio silent. Between upgrading the blog and dodging the flaming dumpster fire that is U.S. politics right now, social media just hasn’t been the vibe. But don’t worry, I’m still building, still planning on writing more, and still helping orhers anyway I can. Hang in there.

Moved my entire *arr suite from 7 LXCs to Docker in one VM.
Networking issues: gone.
Permission headaches: gone.
Update complexity: gone.
Why I feel Docker is better solution than separate LXCs for the *arr suite:

🔗 diymediaserver.com/post/docker-...

Some of you are asking why I brought my Arr stack back to Docker from LXCs. I'll have a post about my reasons soon.

Also others are asking for my complete Docker Compose and .env files. I will share these with everyone soon.

Right now I'm focusing on the blog to bring you a better user experience.

After months of juggling Sonarr, Radarr, SABnzbd, etc. across separate LXCs, I’ve moved the entire Arr stack back into a single Docker VM.

Less overhead, easier updates, and cleaner permissions.

Sometimes consolidation beats isolation.

Testing out Debian 13 (Trixie) for my NAS. Feels a lot less bloated than Ubuntu 24.04. Once released, I'll be migrating all of my VMs and LXC containers back to Debian. I just feels more like home than Ubuntu ever did for me.

How To Install Prowlarr in Docker If you’ve been adjusting your indexers and/or downloaders across Sonarr, Radarr, Readarr, and/or Lidarr by hand, you know it’s repetitive, it’s messy, and it's tedious. Prowlarr allows you to manages ...

I would love to use CEPH but, I don't have the network gear to take full advantage... Yet.

Adding a 3rd Proxmox server to the mix. I might have a problem. Now the question is to cluster or not. I have no need for high availability so leaning to not.

One man said "no more."

Armed with Proxmox, Docker, and a dangerously optimistic MergerFS config..

He built a self-hosted empire with Jellyfin, Sonarr, and sheer stubbornness.
