Error 500 on docker compose - Running 6.x

Hello,

I'm trying to get docker installed (podman would be nice but I don't think there is support for it eh?) but keep running into an error 500 wall.

I have a feeling this might be a common theme since I've seen a few post similar to mine but their resolution isn't lining up with my situation.

The closest I've seen to fix my issue would be this post: Error 500 on docker compose plugin install / GPG error?

It has pretty much the same error code as I but their fix isn't clear and from what I am guessing it was (getting rid of plugins?) it might not be what I need.

I tried the following command on an ssh connection to the nas to no avail and I've also tried disabling the backports from gui but still no luck.

sudo omv-aptclean repos

sudo omv-changebackports NO

sudo omv-upgrade

omv-extras/docker is enabled but when I try 'compose/settings > reinstall docker' I get these error 500 saying:

500 - Internal Server Error Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sb...

I am running omv 6.9.16-1 (Shaitan) on a rPi micro-sd card with an external disk for storage. I was trying to follow the omv-extras guide but they seem to either skip a step or my install wont follow theirs;

In the '2.1 - Simple OMV NAS system' section of the 'Install and Configure Docker' Guide, the screenshot for the compose/settings page where you assign the folders indicates that docker is 'installed and running'.

- Where did the install of docker initially occur? My current setup is giving me a 'Not installed' status yet I have followed the instructions leading up to this.

It can very well be that the issue is me still running on 6.x therefore if an upgrade to 7+ is my next course of action, is there a way to do so without completely recreating my OMV install?

Any help here is appreciated

Cheers,

Red

OMV 6.x is long EOL. Upgrade to OMV 7 then OMV 8.

ok I'm doing that now, pi was running deb11 for omv so before i go too far in the deep end, will upgrading to Bookworm from apt break omv? I tried upgrading omv to 7.x but it's still on 6.9 (nice) after reboot so my guess is to upgrade to deb12

Plan is to upgrade from deb11 to 12 > omv upgrade release > success

fix6to7upgrade script

I'm guessing the script is included with omv? (Asking in case it's in a separate repo or something)

Without seeing the upgrade logs, I can't tell you what went wrong

Here is the tail end of me running omv-upgrade:

Nope. https://github.com/OpenMediaVa…-Developers/installScript

sudo wget -O - https://github.com/OpenMediaVa…raw/master/fix6to7upgrade | sudo bash

Aight so I ran the script and went to the web page to check if anything happened, pushed updates from there too since it was still indicating 6.9.x. Now, the 7.0 web seems to have been updated but i am getting a error 500 anytime I try to login... guessing this is not normal?

edit: I tried the admin account with both the default password and my own that I had changed prior to the update.

So I found this post with a similar error 500 issue as I tried looking at systemctl to see if apache was in the way of nginx but that was not it. I then tried omv-salt deploy run nginx phpfpm and got the following summary(pasted at the end of this reply).

I also tried the usual sudo apt update and upgrade to see if that did anything and somehow the terminal session breaks? I don't know if it has anything to do with me ssh-ing into the pi or else but doing an update gives me:

Building dependency tree... Done

N: More information about this can be found online in the Release notes at: https://www.debian.org/releases/bookworm/arm64/release-notes/ch-information.html#non-free-split

And when I follow it up with apt upgrade I get:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

Running the dpkg command prints out Setting up smartmontools (7.3-1+b1) ... and then ssh times out...

Welp, I am able to access my network storage, so if I can't find a fix for web login I might just pull the storage and rebuild the pi to be on omv8. Not sure yet, will be back with more..

Also, the web interface is giving me a 502 error code now not 500. Indicative of an issue with nginx

How much of the mentioned path is available?

php8.2 is installed, but not configured. Try

Yea I tried that, but it starts smartmontools (?) And terminal session crashes.. could I just apt remove smartmontools?

You can also try

apt install --reinstall openmediavault

noukesal@nas:~ $ sudo apt install --reinstall openmediavault
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a'
to correct the problem.

Since i cant do dpkg -a, I think I'll have to find how to disable smartmontools...
