Install of OMV-extras plugin not working - dpkg: error: PATH is not set

tillstaff · 25. April 2015

Hello,

I'm new to OMV and I have some trouble in installation of plugins.

Here is the message I have :

Code

A reboot solve the problem, but it comes back after while (between 2 plugins installations sometimes).

My OMV installation is a fresh wheezy installation where I installed manually OMV.

Does someone have an idea about my problem?

Thanks for your help.

Hard to say what the problem is since you didn't use the OMV install media. DId you install apt-utils? What instructions did you follow to install omv? Did you google the path error? Lots of results.

tillstaff · 26. April 2015

Hello,

Apt-utils is well installed, there is no problem with the install of package using SSH. I have the problem only with the OMV GUI.

For the installation, I followed this guide : http://forums.openmediavault.o…ult-on-Debian-7-x-Wheezy/
I have only one harddisk drive on my online server, so I can't install OMV by default.

Hello,

After some investigations, I found a log about the failed command.

Code

The same command under ssh/root was ok.

Do you know how the update command is launched through the web GUI? With wich user?

Hello,

I tried to update OMV to 2.0.5 version and it's still the same.
Except I have an error message with more details.

Hello, I've got same issue, any news about it ?

Thank you !

slobberbone · 17. Juli 2015

I answer to myself :

I've got a server in a server provider named OVH with specifi kernels, I choose Debian 7 64 bits for installation then I've done this to have a fully OMV on the server

I follow these steps :

Code

# Note: For OMV-extra-plugin : Do these steps before installing OMV:
apt-get update
echo "deb http://http.debian.net/debian wheezy-backports main" > /etc/apt/sources.list.d/backports.list
apt-get update
apt-get -t wheezy-backports install linux-image-amd64


# Note: Specific OVH
mv /etc/grub.d/06_OVHkernel /etc/grub.d/60_OVHkernel


update-grub
reboot
apt-get install linux-headers-$(uname -r)


# Note: Specific OVH, dns resolution for docker doesn't work
echo "nameserver 8.8.8.8" | tee /etc/resolv.conf > /dev/null
echo "nameserver 8.8.8.8" | tee /etc/resolvconf/resolv.conf.d/base > /dev/null
# Note: You would be able to install all plugin, and more sepcificly the docker plugin now !


# Note: Fix issue : "dpkg: error: PATH is not set"
echo "PATH=$PATH:/usr/local/sbin/:/usr/sbin/:/sbin" >> /etc/login.defs


# Note: Install OMV
echo "deb http://packages.openmediavault.org/public kralizec main" > /etc/apt/sources.list.d/openmediavault.list
apt-get update
  # Note: You may be will have an error like NO_PUBKEY XXXXXXXXXX, then do :
  apt-get install openmediavault-keyring libapache2-mod-php5
  apt-get update
# Note: You will get a warning that the PGP Key can't be found. Thats fine.
apt-get install openmediavault-keyring postfix
# Note: You will get a warning that the package 'openmediavault-keyring' can't be authenticated. You're fine to ignore that warning and install it anyways.
apt-get update
apt-get install openmediavault
omv-initsystem
shutdown -r now

Now I can install all applications I want via Docker !!! YEAH !

slobberbone · 20. Juli 2015

For the main subject of this thread, you are only interested by :

Code

# Note: Fix issue : "dpkg: error: PATH is not set"
echo "PATH=$PATH:/usr/local/sbin/:/usr/sbin/:/sbin" >> /etc/login.defs

The you may have to reboot to take effect

ikogan · 15. September 2015

This problem just started happening to me recently and I'm not sure why. Editing login.defs doesn't help. `apt-utils` is installed. Here's what I'm getting from the GUI:

Code

This is on a long time install from the installation media. Though I did have to mess with grub after installing openmediavault-zfs. I'm not sure what that would have to do with this error though.

nicjo814 · 30. Dezember 2015

@ikogan Were you able to fix this issue? I get it in your omv-docker image (which otherwise works like a charm!).

ikogan · 30. Dezember 2015

Is it with the couchpotato package or in general? I'm not having it happen anymore but I don't remember what I did.

nicjo814 · 30. Dezember 2015

I get dpkg: error: PATH is not set for every package I try to install/upgrade when done via the "update manager". Manually running apt-get works fine though... This is on a fresh docker image.

davidh2k · 30. Dezember 2015

I encountered the same problem months ago, could never figure it out...

Greetings
David

ryecoaaron · 30. Dezember 2015

I've seen people post about this many times but have no idea what causes it. Never been able to reproduce it.

nicjo814 · 30. Dezember 2015

It's like the "web interface user" does not have PATH set... Running apt-get as a "normal" user in cli works fine.

ryecoaaron · 30. Dezember 2015

Just don't know how the user looses the path settings.

ikogan · 1. Januar 2016

I remember doing something specific to fix it and I can't remember what...

mikael · 3. Januar 2016

It seems this problem stems from a bug in setproctitle(): when omv-engined calls setproctitle($cmdName), it overwrites the first 69 bytes of the environment with spaces. This is easy to see by by cat'ing the "environ" file in the /proc entry of the process.

This problem is described here: http://php.net/manual/en/function.setproctitle.php#112003

On my setup, the problem started showing up when I restarted the engine with "service openmediavault-engined restart", as per @SVS's Guide. The terse environment due to the use of the "service" command moved the PATH to the beginning of the environment, causing it to be overwritten upon setproctitle() invocation. When I restarted the engine manually ("/etc/init.d/openmediavault-engined restart"), the larger environment pushed the PATH variable far enough to be spared.

ryecoaaron · 3. Januar 2016

It is just odd that I have never had this problem on any of my systems including all the test VMs.

nicjo814 · 3. Januar 2016

Thanks! I'll make sure to test with cli_set_process_title() instead.

Jetzt mitmachen!
