**System info:** - umbrelOS 1.5.0 (amd64, x86 custom hardware) - Debian GNU/Linux 13 (Trixie) - Kernel: 6.12.48+deb13-amd64 - Node.js: v22.13.0 - Mender client: 3.4.0 (Debian package) - Hardware: 16GB RAM, 2TB NVMe SSD, Intel/AMD x86 **Problem 1: umbreld (node process) crashes every ~36 hours** The `bitcoind` container restarts every ~36 hours, resetting the “Running time” counter in the Bitcoin Node app. After investigation via SSH, the root cause is a General Protection Fault in the `node` process (umbreld): kernel: traps: node[705652] general protection fault ip:7f525ab4450f sp:7ffc78c40020 error:0 in libc.so.6[2650f,7f525ab44000+156000] This has happened **10 times** since March 22, always at the same instruction offset (`+0x50f`) inside `libc.so.6`, with a consistent interval of ~33-40 hours: Mar 27 22:08:43 - node[2981] GPF in libc.so.6 Mar 30 22:18:32 - node[213523] GPF in libc.so.6 Apr 01 07:34:25 - node[322797] GPF in libc.so.6 Apr 02 16:08:33 - node[372698] GPF in libc.so.6 Apr 04 03:50:37 - node[421644] GPF in libc.so.6 Apr 05 15:37:28 - node[479463] GPF in libc.so.6 Apr 07 00:50:56 - node[532484] GPF in libc.so.6 Apr 08 17:52:40 - node[582162] GPF in libc.so.6 Apr 10 04:12:22 - node[643172] GPF in libc.so.6 Apr 11 17:36:33 - node[705652] GPF in libc.so.6 The crash is reproducible and deterministic — same offset every time, ruling out random hardware failure. RAM health check (EDAC) shows no memory errors. The OS itself stays up (21+ days uptime). Only the node/umbreld process crashes, which Docker detects and restarts the Bitcoin container. The crash appears to be a **memory leak or heap corruption in umbreld** that after ~36h triggers a GPF in libc. **Problem 2: Unable to update to 1.6.x — Mender incompatibility** The automatic update system does not offer any update beyond 1.5.0. Manual update via `sudo mender install` fails with: ERRO: Reading headers failed: installer: failed to read Artifact: reader: can not read version file: readNext: Failed to get next header: reader: error reading archive: archive/tar: invalid tar header Investigation revealed that the bootstrap artifact uses \*\*Mender format version 3: \*\* {“format”:“mender”,“version”:3} But the Mender client installed on the system is version **3.4.0** (from Debian Trixie repos), which does not support format v3. Mender 4.x/5.x from Northern.tech requires paid dependencies (403 Forbidden on download). There is no Mender package available for Debian Trixie. The `artifact_info` file also had an incomplete entry (`artifact_name=umbrelOS` without version number), suggesting Mender was never successfully used on this device since initial installation. **What I tried:** - Enabled umbrelOS Beta Program toggle — no update offered - Manual `sudo mender install https://download.umbrel.com/release/1.6.1/umbrelos-amd64.update` — fails with invalid tar header - Corrected `artifact_info` to `artifact_name=umbrelOS-1.5.0` — same error - Used `--config /data/mender/mender.conf` flag — same error - Attempted to install `mender-client4` (5.0.1) — dependencies blocked with 403 Forbidden **Request:** 1. Is there a fix or workaround for the umbreld GPF crash on Debian Trixie / Node.js v22? 2. Is there a supported way to update from 1.5.0 to 1.6.x on x86 hardware when Mender is broken? Thanks in advance!
