dnf downgrade dependencies

[Dave Close]

I've decided I'm unhappy with one of the changes made by the most
recent version of LibreOffice, 24.8, and I want to try going back to
the previous version, 24.2, which is part of the FC40 repository.
But I'm astounded by the result of the command below. (Without
allowerasing the command won't do anything.)

dnf downgrade --allowerasing --enable-repo=fedora40,updates40 \
    libreoffice-24.2.2.1-3.fc40.x86_64
  ...
  Transaction Summary:
   Installing:        21 packages
   Upgrading:          8 packages
   Replacing:       1169 packages
   Removing:          13 packages
   Downgrading:     1161 packages

This is effectively returning to FC40, not just downgrading a single
package. Of course, I didn't follow through.

But somehow DNF thinks the following packages are dependent on 
LibreOffice: mplayer, opencv, python3-crypt-r, tesseract-libs, x264,
among others! And it thinks the removal of these packages requires
downgrading others, including mod-perl!

I suppose I can simply download the older LibreOffice packages and then
use rpm to replace them. But there could be some authentic library
dependencies. Is there a better solution?

libreoffice has many dependencies and if you downgrade those to what 
that version needs, then you have to also downgrade all the packages 
that depend on those dependencies.

You don't need to setup your own repo files for this.

dnf --releasever=40 install --allowerasing 
libreoffice-24.2.2.1-3.fc40.x86_64

But that won't help you any.  You can't do this.  Here's a big clue when 
run without the --allowerasing:
Problem: package libreoffice-pyuno-1:24.2.2.1-3.fc40.x86_64 from fedora 
requires python(abi) = 3.12, but none of the providers can be installed
   - package libreoffice-base-1:24.2.2.1-3.fc40.x86_64 from fedora 
requires libreoffice-pyuno(x86-64) = 1:24.2.2.1-3.fc40, but none of the 
providers can be installed
   - cannot install both python3-3.12.2-2.fc40.x86_64 from fedora and 
python3-3.13.2-1.fc41.x86_64 from @System
   - cannot install both python3-3.12.9-1.fc40.x86_64 from updates and 
python3-3.13.2-1.fc41.x86_64 from @System
   - package libreoffice-1:24.2.2.1-3.fc40.x86_64 from fedora requires 
libreoffice-base(x86-64) = 1:24.2.2.1-3.fc40, but none of the providers 
can be installed
   - installed package python3-google-re2-1:20240702-19.fc41.x86_64 
requires python(abi) = 3.13, but none of the providers can be installed
   - conflicting requests
   - problem with installed package

The first problem is that it requires Python 3.12.

Well then, I suppose I could download the source package and try to
build it on FC41...

Sent a longer reply to Dave Close.

But you can have both the Fedora version of Libre Office and a 
Libre Office version at the same time. They can be installed at same 
time.

On my Fedora 41 machine I have the two versions running.
So, I'm doing the reverse of what he wants. I have the default 
24.8.5.2 version of Fedora 41 and have the newer 25.2.1.2 version.
Installing the LibreOffice version puts the files in /opt directory, 
while the Fedora version is in its location. Menu shows both.
Just showing writer packages as example.
libreoffice25.2-writer-25.2.1.2-2.x86_64
libreoffice-writer-24.8.5.2-1.fc41.x86_64

# which libreoffice
/usr/bin/libreoffice
# which libreoffice25.2 
/usr/bin/libreoffice25.2
# ls -l /usr/bin/libreoffice25.2 
/usr/bin/libreoffice25.2 -> /opt/libreoffice25.2/program/soffice

So, except for doubling the space to have two versions for testing.

Doesn't show any issues that I've seen? But limited testing.
