Prevent Fedora from downgrading Synergy

Updated

Product: Synergy 3
Operating system: Linux

 

After installing Synergy 3 on Fedora, you may notice after a while that Synergy gets automatically downgraded to Synergy 1/Deskflow or removed by the operating system when updating or restarting the computer.

This is caused by a bug in our RPM package generator not using the correct epoch value, which we plan to fix. Until then, here's a workaround to stop Fedora from automatically downgrading or removing Synergy 3.

If Synergy has already been downgraded to a different version, please uninstall it and then carry out the steps below:

  1. Install Synergy again via terminal - sudo dnf install ~/Downloads/synergy-3.3.1-linux-noble-x64.rpm
    (This example is based on the Synergy 3.3.1 installer file for Noble, please use the relevant installer file name after /Downloads/ for the version of Synergy that you have downloaded)
     
  2. After you have installed Synergy please make the changes below which will prevent Fedora from downgrading the version of Synergy installed
     

Newer versions of Fedora

  1. Edit /etc/dnf/dnf.conf
  2. Under [main] add: exclude=synergy


Older versions of Fedora

  1. Edit /etc/yum/repos.d/fedora.repo
  2. Under [main] add: exclude=synergy

 

Please note that if you would like to update Synergy 3, you would first need to remove exclude=synergy under [main], proceed to update Synergy 3, then add exclude=synergy under [main] after updating to prevent Synergy from downgrading again.
