Unable to update OMV from package manager in fresh OMV 6 install

Silvaire · 2. Juni 2022

Hi, I recently started with a fresh install of OMV 6 to replace my OMV 5. Everything has been fine, but I noticed that I cannot update the OMV package itself either through CLI or GUI. I get the following permission error:

Code

Preparing to unpack .../openmediavault_6.0.28-3_all.deb ...
Unpacking openmediavault (6.0.28-3) over (6.0.28-2) ...
Setting up openmediavault (6.0.28-3) ...

Not sure how to proceed. Thanks!

This folder doesn't exist for me, nor do I normally use rsa authentication for anything. I just use a password to authenticate through SSH.

Try.

Code

root@omvad3:~# ls -la .ssh
total 20
drwx------ 2 root root 4096 Mar  4 09:00 .
drwx------ 5 root root 4096 Mar 18 11:59 ..
-rw------- 1 root root  564 Mar  4 09:00 authorized_keys
-rw------- 1 root root 3369 Mar  4 08:55 id_rsa
-rw-r--r-- 1 root root  737 Mar  4 08:55 id_rsa.pub
root@omvad3:~#

id_rsa is a file not a directory.

Whoops, in any event, I don't have that file either. Not sure why it's being invoked now as a blocker to updating the OMV package and only the OMV package.

That file should be there because OMV generates it. It is failing to generate it now since it isn't finding what it wants - https://github.com/openmediava…nmediavault.postinst#L159

Try running: sudo ssh-keygen -t rsa -N "" -f /root/.ssh/id_rsa then sudo apt-get -f install

Thanks, unfortunately it looks like it's the same activity the package manager upgrade is doing and failing with:

What is the output of: grep -w '/' /proc/mounts

What about: stat /root/.ssh

What kind of media is the OS installed on? Can you rm -rfv /root/.ssh?

OS installed on a new SSD. FWIW, I also have the flashmemory plugin installed.

Code

root@Paragon:/srv# rm -rfv /root/.ssh
rm: cannot remove '/root/.ssh/authorized_keys': Operation not permitted

How are you accessing the machine? Console, ssh, putty or something else.

If you can't remove something as root, I suspect the media is bad even if new. What kind of ssd?

I can access the machine through IPMI, ssh, and the webGUI. In the above examples, I'm using ssh, but I get the same error in both ssh and webgui.

This: https://www.amazon.com/gp/prod…_asin_title?ie=UTF8&psc=1 + a brand new SATA cable.

I will say I've not noticed any other issue, and have noticed a significant performance increase (my old SSD was dying). I've had no complaints about OMV 6 or the install process, or re-setting up anything, from either a HDD or permissions failure up until this point. I've been able to install any other package fine. It's just this particular action blocking the installation script from installing the OMV update.

I did just reboot, no dice. I tried googling this issue first, but surprisingly came up with very little on such a generic error message like "operation not permitted."

This is a pretty big issue though. All it takes is for one file like this to be on a bad sector. Do you see any messages in dmesg when trying to delete it? If you can, I would boot the system with something like systemrescue, mount the filesystem, and try deleting it.

Silvaire · 3. Juni 2022

Thanks, will keep fiddling with it and see what I can discover. Re: running from a rescue OS, I used to rely on the one-click install and run from the omv-extras repo--I'm assuming that's not available (yet) for OMV 6?

Silvaire · 3. Juni 2022

OK good news is I fixed it. I followed this thread:

https://unix.stackexchange.com…even-when-running-as-root

I'm not a Unix permissions guru by any means, but apparently there was an "immutable" flag set on the .ssh folder that had to be removed before it could be modified, even as root.

I don't know how the -i flag got set on that folder. But hopefully it helps for someone else that may experience this issue in OMV 6. FWIW, I'm using flashmemory, symlink, mergerFS, and snapraid.

Jetzt mitmachen!
