Package dependency issue, not sure safest way to proceed

  • 772

I am running into a package dependency issue. Can someone help make sense of how to resolve this?

Q What steps do i need to take when it says Requires: zfs-kmod = 0.7.7 Available: kmod-zfs-0.6.5.11-1.el7_4.x86_64 (zfs-kmod) for e.g. do I need to remove them, are they in cache and the cache needs to be cleaned?

What triggered this, is I'm using zfsonlinux, and moving from DKMS to Kabi Tracking method. I have already removed DKMS modules per the docs, which seems to go off without a hitch, however something along the lines got out of sync.

/etc/yum.repos.d/zfs.repo

  1 [zfs]
  2 name=ZFS on Linux for EL7 - dkms
  3 baseurl=http://download.zfsonlinux.org/epel/7.4/$basearch/
  4 enabled=0
  5 metadata_expire=7d
  6 gpgcheck=1
  7 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux
  8
  9 [zfs-kmod]
 10 name=ZFS on Linux for EL7 - kmod
 11 baseurl=http://download.zfsonlinux.org/epel/7.4/kmod/$basearch/
 12 enabled=1
 13 metadata_expire=7d
 14 gpgcheck=1
 15 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux
 ...

When I try to install: 

 $ sudo yum install zfs

     You could try using --skip-broken to work around the problem
     You could try running: rpm -Va --nofiles --nodigest

It looked like --skip-broken would work, when i tried it, but i didnt let it complete, didnt say yes to it.

Q I'm not sure what rpm -Va --nofiles --nodigest is, would that help?

Q I Did try to temporarily enable disabled repos, that didnt work.

Here is what I see installed now: (currently nothing showing up for dkms, spl, zfs)

$ sudo yum list installed | grep zfs
Repository nodesource is listed more than once in the configuration
Repository nodesource-source is listed more than once in the configuration

$ sudo yum list installed | grep kmod
Repository nodesource is listed more than once in the configuration
Repository nodesource-source is listed more than once in the configuration
kmod.x86_64                      20-15.el7_4.7           @rhel-7-server-rpms
kmod-libs.x86_64                 20-15.el7_4.7           @rhel-7-server-rpms
python-kmod.x86_64               0.9-4.el7               @anaconda/7.2

Even when I install zfs-release sudo yum install http://download.zfsonlinux.org/epel/zfs-release.el7_4.noarch.rpm I get the same kmod package error.

Another couple steps i took, which didnt help is the following, but i still have the same symptoms. 

$ sudo yum autoremove
$ sudo yum clean metadata

Im not sure how to repair this, so that i can regain ZSF file access.

Q How should I proceed?

yum
