Dear Flavio,

There are no updates available for PyRx 1.0 for Linux.

Update of version 1.1 to 1.2?

Flavio Augusto Vicente Seixas — Thu, 05 Mar 2026 16:49:18 -0000

Dear Sarkis.

I recently purchased academic license for PyRx 1.0 for Linux and managed to install it on a PC running Ubuntu 24.04.

However, when running the program as root and checking for updates, I received the following message:

Error in: <function checkforupdates="" at="" 0x1f736410="">
args: Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.</function>

Could you help me

Flavio

PyRx 0.9.3 on Fedora 43 not starting up

Thank you very much! That helped. It gave me enough info to determine that I needed to install Gtk2. PyRx started right up after installing Gtk2.

Edit run.sh and replace:
$PYRX_HOME/bin/python $PYRX_HOME/runPyRx.py &> /dev/null
with
$PYRX_HOME/bin/python $PYRX_HOME/runPyRx.py
When you run from the command line it should tell what libraries are missing.

Apologies for the delay. The forum didn't send me an email like it used to do to let me know when there is a reply.

I tried that today. When I ran that command, it said that there was nothing to install, likely because it was already installed from when I installed it previously. I re-ran the install commands for all three of those packages to make sure they were installed, and all of them were already installed. I even tried uninstalling PyRx and reinstalling it after running the three install commands again. PyRx is still not starting up when I click on the app icon or when I try to start it from the command line. I even tried installing PyRx without sudo to see if there might be permissions issues with the PyRx-specific files when I install it using sudo, but that did not work either.

I was able to start PyRx after yum install sdl12-compat.x86_64
Please let me know if it works.

Thank you for the message. I plan to install Fedora 43 over the weekend. I'll keep you posted on the progress.

PyRx 0.9.3 on Fedora 43 not starting up

I have a purchased version of PyRx 0.9.3 that was previously running with no issues on Fedora 42, which had been upgraded numerous times from earlier versions. Recently, I had to do a clean installation of Fedora 43. When I reinstalled PyRx, it would not start up. I followed the instructions on the download website to install libpng12.x86_64, SDL.x86_64, and mesa-libGLU.x86_64. (These instructions are still the same on the PyRx downloads website as when I first downloaded v0.9.3.) Mesa-libGLU was already on the system, libpng12 was installed, and SDL was not found in the repository, since Fedora is now running SDL3. I installed sdl2-compat and sdl12-compat to try to cover for the lack of sdl, but nothing is still happening when I try to run PyRx. Any suggestions would be greatly appreciated.
