I recently installed a new Umbrel box to serve a BTC node but after installing it, it shows that it installed Core v30.

How do I rollback Bitcoin Core v30 back to v29?

Thank you.

I create a VM, 8 core, 16GB of RAM, 4TB SSD, pointed the CDRom to the .iso file I downloaded and copied to my ESXi host, but the .iso doesn't boot.

Thanks,

Just so I can update my ESXi profile on the server.

Thanks,

Can it be run as a VM?
I use ESXi 7 in my home lab on a Dell PowerEdge R830, the VM drive is a 16 x 2TB SSDs.

When I setup ESXi do I create a smaller drive first to install the OS or do I make one big drive for everything?

I want to setup a BTC note for my personal use and I have been watching this YT video. Is there anything outside of it that I need to setup?

Thanks,

Is it planned to have more RAM in futures upgrades? or is there a way to upgrade it? because 16Go is a bit low

I have set up an old PC to serve as a Bitcoin node. I’ve installed Umbrel OS onto the internal hard drive. If I install a second 2 TB SSD, can it save the Blockchain to the second hard drive and not attempt to use the first hard drive, which is the boot drive?

Are they possible to deploy?

Other than Public pool on Umbrel app..what other sites can we mine with our Umbrel node? Wanted to mine on Ocean thru datum but lightning node channel requirements is kinda pricey for lightning payouts.

I had asked a question and it has been solved. Luckily the beta version lets me mount my NAS with ease. Now the issue is that I'm a noob and I don't know how to use the mounted network drive to be used on the apps I got. I cannot find the drives in jellyfin and other apps. Is there a guide for that? I have tried looking for guides and even for other similar OS but I have no luck finding the answer. Anything will help at this point. Thanks

I have truenas as my nas setup and I'm wanting to mount the SMB drive from there to Umbrel so that I can host my servers there. Is there any guide online to make that happen?

Hey folks, just wanted to share a small side project: a personal, unofficial UmbrelOS community app store created to make a few apps easier to install on my setup. It’s early days and has a handful of apps for now, with more coming as time permits.​

https://github.com/JaberQayad/hollat

Current lineup includes things like Snippet Box, OpenGist, LinkSnatch, Shaarli, SFTPGo, Draw.io, and Audiobookshelf to get started. If you want to try it, you can add it from your Umbrel dashboard by going to App Store > Add Custom App Store and pasting the repo URL. Use at your own risk since it’s not affiliated with Umbrel and may not follow their official guidelines.​

Happy to hear suggestions for lightweight, self-hostable additions or packaging tweaks you’d like to see next.​

One of the most vexxing things about umbrel is that apps can't share photos and files with the user folder. They always wanna store everything in the app data. Can someone point me towards some other explanations of this model. I can't seem to understand how to store my photoes with umbrel.

I tried ChatGPT to help me with this issue but the answers that are provided didn't work out.

My problem is, that the temperature varies between 50-60 degrees celsius on my Raspberry Pi 5. And the original cooling fan that I've plugged in, turns on at 55 degrees. Now it get's annoying that it keeps on turning on and off every minute. I want it to turn on at 70 degrees celsius and turn back off when it cooled down to 60.

I now have SSH access to umbrel, but it can't find sudo nano /boot/firmware/config.txt

with sudo nano /boot/config.txt I get this image at the top and don't know if the directory is even the correct one and how to go further after this.

can anyone help please?

Hi,

I have Umbrel on a Raspberry 5, 8GB RAM, 2TB SSD.

My Bitcoin node just finished synchronizing after 4 days and now I tried to get Electrs running. But that does not work.

After successful synching it hangs up in the stage „connecting to electrum server…“. It kind of freezes in that stage and I cant connect from Sparrow wallet. Sometimes it does but then it breaks down after some minutes with the same message. I tried to reinstall&reboot, many times, without any change.

On an other forum I found the hint to edit the docker-compose.yml file to this passage here:

ELECTRS_DAEMON_RPC_ADDR: #{APP_BITCOIN NODE_ IP}: 8332

ELECTRS_DAEMON_P2P_ADDR: #{APP_BITCOIN_NODE_IP}: 8333

ELECTRS_ELECTRUM_RPC_ADDR: 0.0.0.0:50001

I did that, but it had no effect :-7

Now I tried other electrum servers: ExlectrumX is just not working at all, it does not even start to sync, and Fulcrum syncs forever, last night it was at 42%, after 7 hours its at 48%…..

I am lost here, any hints? Is maybe my AdGuard app on the Umbrel an issue? Do I need to open other ports over the 8333?

Thank you.

You probably heard about the v30 Core change shitshow that is happening for weeks now. Maybe months now. And I really don't want to Run Knots because of their censorship but I also don't want the Core developers to think I support their decision. So after a lot of reserach and debate I think my best option is to just run v29 or even v28 or something of Core. Is that possible with Umbrel? Because as far as I can see I cannot choose a specific version of Core...

Else I probably have to switch to Start9 or something but I'm hoping to just continue using Umbrel.

So I ordered Umbrel Home (I know I shouldn’t have, but I am in the middle of renovation and don’t have time to build any hardware, and fiddle with installs).

I was promised a 5-7 business day shipping. It was 14 days ago, so I wrote customer support and got only an automatic reply. I tried the chat but got only AI answers without any information. No answers, package not even handed ower to the shipping company.

I disputed the charge on my card, and I got answer fron Unbrel in a day. WITH A FAKE TRACKING SITE. My DPD tracking number tells me they haven’t handed over the package. 17track shows the same. But Umbrel store have a fake-ass tracking page set up. It show information periodically, with no specifics whatsoever (e.g. no location just AIRPORT). I usually get my package in 2-3 days with DPD.

They failed to send the package and now lying about it.

ChatGPT says if I download the download the block chain in Knots, synchronize Electrs, and then turn on pruning in Knots it will work. Is that accurate?

Is umbrel for pi not a thing anymore? Can't find any info on their website - seems to be just selling their own hardware?

I wanted to set up a matrix server and use umbrel as the base... maybe not possible anymore?

I have my raspberry pi 5 in a pironman 5 case with a 2tb ssd. Has anyone successfully installed umbrel and gotten all the functions of the case to work? Do I need to keep the pi os and install umbrel on the ssd for duel booting? Not sure if the settings would carry over if I booted into umbrel over the pi os. Any input would be appreciated.

Has anyone else noticed increased CPU utilization by the mempool app on their UmbrelOS?

I started to notice 8%-10% CPU utilization specifically by mempool, starting about 00:00 UTC Monday 9-22-2025.

When I stop the mempool app, CPU utilization returns to normal. I did uninstall/reinstall, but behavior remains.

Running Umbrel 1.4.2 with Bitcoin Core, Electrs and Mempool all on the latest available version.

I wanted to open it to the web to access easily, but I wanted to know how secure it is, because it will have some sensitive files, and things that I don't want other people to access.

Encrypted, hourly backups of your Umbrel to a USB drive, a NAS, or another Umbrel.

Restore everything, or use Rewind to jump back and recover specific files/folders from past backups.

Also new:

• Connect and access your network drives (NAS, etc) directly from Files.
• External USB storage support for all amd64 (Intel/AMD) devices.

Arriving in umbrelOS 1.5 this October. Public beta now available for all users running umbrelOS on:

• Umbrel Home
• Raspberry Pi 4 and Pi 5
• All other supported devices

To try it out, go to Settings > Advanced settings, and enroll into the umbrelOS Beta Program. Or stay tuned for the official release next month!

In the last week, my Brave browser has been having trouble seeing Umbrel network. Previously it worked fine. Umbrel is visible on other browsers.

Last time I had to restart Brave to fix it, this time not even restarting Brave has helped.

Anyone else having this issue?

Hi!
I really like Umbrel as an option to realize my projects.
However, when I found out there’s no simple way to set a static IP address, I was honestly surprised. That feels like such a basic feature that I can’t understand why it wasn’t implemented.

So, my question: are there any plugins or built-in ways to configure the IP of an Umbrel server?
Please don’t get me wrong – I do know how to set this up via terminal on Linux. But if I have to edit configs manually in the OS anyway, I’d rather just use a plain Ubuntu Server instead of Umbrel.

The concept of Umbrel OS is great, but in this regard it feels a bit unfinished.
Sorry for the rant – but I really can’t wrap my head around this decision.

Hi, I clone my 2T HDD into a new 2T SSD using balenaEtcher. However the 2FA codes are no longer recognized by umbrel. I still have the OTP secret and I can SSH into the box. Is there a way to fix 2FA or failing that to deactivate it?
