Broken Update n8n to 2.36.8
-
The app is stuck in a permanent restart loop. On every boot, the EXTRA_NODE_MODULES install step fails with:
npm error code EACCES npm error syscall mkdir npm error path /home/cloudron/.npm/_cacache/tmp npm error Your cache folder contains root-owned filesBecause that install never completes, n8n never binds to port 5678, so the healthcheck fails with ECONNREFUSED/EHOSTUNREACH and the container restarts, repeating the same failure every 15 to 20 seconds.
So the directory can't be fixed from outside the app either. This looks like the same class of issue reported in older threads about handlebars and community node installs, where /home/cloudron/.npm sits on a read-only filesystem and npm's default cache path can't be written to.
Packages configured: handlebars, jsonata, marked, bwip-js, ajv-formats, odoo-xmlrpc, firebase-admin.
Is there a supported writable cache path we should be pointing EXTRA_NODE_MODULES at, or is this something that needs a package fix?

I have revoked the package. @divemasterza can you paste more of the raw logs please? You can put it at https://paste.cloudron.io

I debugged this on my instance with Claude Code and found what looks like the actual root cause, sharing here in case it helps.
Root cause (confirmed via docker exec):
/home/cloudron inside the container is owned by 998:998 with mode 750:$ docker exec <cid> ls -lan /home/ drwxr-xr-x 1 998 998 4096 Aug 7 14:46 . drwxr-x--- 1 998 998 4096 Sep 1 10:59 cloudronBut
start.shrunsgosu cloudron:cloudron npm install ...and that user isuid=1000(cloudron)gid=1000(cloudron). Since998:998isn't in that user's groups and the dir is750, UID1000has zero traversal access to/home/cloudron- it fails on the very first path component, not just on_cacacheownership. That's also why thechown -R 1000:1000 ~/.npmsuggestion in the npm error message doesn't actually help here.On top of that,
/home/cloudronis baked into a read-only image layer: chown as root inside the running container fails with "Read-only file system" on every file under it. So it can't be patched at runtime - it needs a fix in the image build (chown /home/cloudron to 1000:1000at build time, or align the cloudron user's UID/GID with998).Workaround that avoids touching /home/cloudron entirely, added to env.sh:
export NPM_CONFIG_CACHE="/run/n8n/custom-node-modules/.npm-cache"This redirects npm's cache to a path start.sh already chowns to cloudron:cloudron before running the install step. Confirmed working on my instance - install succeeds and n8n starts normally with this in place.
Hope this saves someone some time, happy for the team to take it from here.
