Description Jaroslav Škarvada 2014-11-03 20:50:57 UTC

Description of problem:
Older kernel cannot be installed.

Version-Release number of selected component (if applicable):
dnf-0.5.4-2.fc20.noarch

How reproducible:
Always

Steps to Reproduce:
1. Install mst copr repo: https://copr.fedoraproject.org/coprs/airlied/mst/
2. Install 3 successive kernel versions from the fedora updates repo
3. dnf install kernel-3.15.8-200.mst.fc20

Actual results:
Chyba: conflicting requests

Expected results:
Removal of the oldest kernel from the 3 installed kernels and installation of the kernel-3.15.8-200.mst.fc20

Additional info:
yum has no problem with such downgrade:

# yum install kernel-3.15.8-200.mst.fc20

Comment 1 Honza Silhan 2014-11-04 15:32:36 UTC

Thanks for the report. Can you try it with downgrade command with `--allowerasing` option, in f21 if you can, please? or upload dubugdata [1].

Comment 2 Jaroslav Škarvada 2014-11-05 14:09:39 UTC

Tried on latest Fedora 21, dnf-0.6.2-1.fc21.noarch and the following seems also weird:

Package kernel-3.8.13-100.fc17.x86_64 is already installed, skipping.
Error: Nothing to do.

Yum shows problems (at least):
# yum install 'https://kojipkgs.fedoraproject.org//packages/kernel/3.17.1/304.fc21/x86_64/kernel-3.17.1-304.fc21.x86_64.rpm'

               kernel-core-uname-r = 3.16.1-301.mst.fc21.x86_64

Btw by doing dnf autocomplete the following error shows up:
# dnf install ./kercut: you must specify a list of bytes, characters, or fields
Try 'cut --help' for more information.

"cut: you must specify a list of bytes, characters, or fields
Try 'cut --help' for more information."

I will probably open another bug for the autocomplete problem.

By using all the deps:
# dnf install ./kernel-3.17.1-304.fc21.x86_64.rpm ./kernel-core-3.17.1-304.fc21.x86_64.rpm ./kernel-modules-3.17.1-304.fc21.x86_64.rpm

Package kernel-modules-3.17.2-300.fc21.x86_64 is already installed, skipping.
Error: Nothing to do.

Yum has no problem with this.

I will provide debug data for this and the previous problem in the next comment.

Comment 3 Jaroslav Škarvada 2014-11-05 14:13:59 UTC

The --debugsolver option didn't create any debug directory for the previous command. I will try downgrading with --allowerasing.

Comment 4 Jaroslav Škarvada 2014-11-05 14:26:24 UTC

So I put the system to the following state (by using yum):
# dnf list kernel

Comment 6 Honza Silhan 2014-11-10 14:16:56 UTC

Thanks for the report. IMO dnf couldn't find package because of (In reply to Jaroslav Škarvada from comment #4)
> # dnf downgrade --allowerasing kernel-3.16.1-301.mst.fc21
> No match for available package: kernel-3.16.1-301.mst.fc21.src

This is weird. Can you attach /var/cache/dnf archive (especially airlied-mst.solv and @System.solv), please?

Comment 7 Jaroslav Škarvada 2014-11-10 15:03:07 UTC

Unfortunately the archive is too big to be attached to bugzilla, so linking it:
https://fedorapeople.org/~jskarvad/dnf/dnf.tar.xz

Comment 8 Radek Holy 2015-01-16 16:19:26 UTC

FTR: according to the expected behavior of the "install" command, "dnf install" should do what Jaroslav wants in this case. (Just to make clear that the problem is not just with the "downgrade" command.)
