    • VirtualBox and ZFS plugins installation issue after fresh OMV install

      Hello,

      i've set up my second, fresh OMV installation v. 4.14 and now i'm trying to install VirtualBox plugin and ZFS plugin from OMV-Extras. But it gives me this kind of error:

      Source Code

      1. The following information may help to resolve the situation:
      3. The following packages have unmet dependencies:
      4. openmediavault-virtualbox : Depends: linux-headers-686-pae but it is not installable or
      5. linux-headers-amd64 but it is not going to be installed
      6. E: Unable to correct problems, you have held broken packages.
      7. <<< *************************************


      When i try to install "linux-headers-amd64" i get this message:

      1. Following packages have unmet dependencies:
      2. linux-headers-amd64 : Depends: linux-headers-4.15.0-0.bpo.2-amd64 but is not going to be installed
      3. E: Cannot resolve the problems, stopped broken packages.
      And when i try to install linux-headers by this command: "apt install linux-headers-$(uname -r)" i get:

      1. The following packages have unmet dependencies:

      3. E: Cannot resolve problems, stopped broken packages.



      How can i resolve this?

      Same issue with Virtualbox after kernel update to 4.15.

      Booting with kernel 4.14 solve the problem and Virtualbox has no problems.

      How can Virtualbox run with kernel 4.15
      I've tried to boot with 4.14 kernel, also installed OMV one more time v 4.0.3 but still VirtualBox and ZFS plugins cannot install with above error. No matter which kernel i use or which OMV version i install.

    • Debian has to fix the dependencies in their control file. I will look for a bug report and report one if I don't find one (if I have a chance). Nothing you can do until then due to the dependency on the linux-headers-amd64 meta package which references the 4.15 headers.

      Thank you for your attention. I hope they will fix this soon because virtualbox is my must-have on OMV :) Also OMV is my must-have already after migrating from Qnap.

    • I just submitted the bug report to Debian. Just have to wait now.

      Do you have a link to your bug report in the debian tracker?

      I encountered the same issue on Saturday, I've done an downgrade to the 4.14 kernel.

      Is there anybody that can answer the following question:
      Is there an improvement for the ZFS Plugin with the newer backports kernel instead of the stable kernel?
      I would say no.

      I was thinking about to use the stable kernel instead of the backports. I have no hardware issues with the stable kernel. Is there any side effects with OMV if I use the stable kernel?

      No since the zfs code is not in the kernel. It may improve support on some hardware though.

      Nope, it works fine. Just add OMV_APT_USE_KERNEL_BACKPORTS="NO" to /etc/default/openmediavault and then omv-mkconf apt. This will prevent the backports kernel from being installed. It won't remove it if it is currently installed though.

    • I guess installing the meta package doesn't resolve dependencies properly but this will:

      apt-get install -t stretch-backports linux-headers-4.15.0-0.bpo.2-amd64

      Updating to omv-extras 4.1.3 should eliminate the need to fix this manually.

      Nope. You just need to compile the zfs module for the new kernel. Then rebooting is the easiest way. You might have to import your pools. In the future, I wouldn't blindly install kernel updates especially when it is a new version.

      This could solve the problem of not installing Virtualbox. I also did an "apt-get update" and "apt-get upgrade" and after reboot I could install Virtualbox without any problems

      Thanks for omv-extras 4.1.3

      Not Virtualbox 5.1.30. I will have to try to build 5.2.8 from the buster repo. If it builds on stretch, the module should compile with the 4.15 kernel since that is the standard buster kernel.

      I guess installing the meta package doesn't resolve dependencies properly but this will:

      apt-get install -t stretch-backports linux-headers-4.15.0-0.bpo.2-amd64

      Updating to omv-extras 4.1.3 should eliminate the need to fix this manually.
      It fixes problem with virtualbox installation, but not with ZFS plugin. When i try to install it via WebGui i just get "Completed..." message immediately after clicking "Install". And nothing else happens, zfs plugin is not available.

      You are correct that it doesn't compile the zfs module but it does fix the issue where the module won't compile. dpkg-reconfigure zfs-dkms

      Also i updated my omv-extras to 4.1.3 without any success
      Same issue after reinstallation of openmediavault-zfs
      If the headers aren't installed, the zfs issue can't be fixed. What is the output of grep -ir backport /etc/apt/*
      omv 4.1.15 arrakis | 64 bit | 4.15 proxmox kernel | omvextrasorg 4.1.13
