Desktop (please complete the following information):
I also had this problem while updating to 2.6

I had the same issue. I had to force overwrite
sudo dpkg -i --force-overwrite /var/cache/apt/archives/com.github.alainm23.planner_2.6.2_amd64.deb
@rbribeiro It's a momentary solution, I'm sending an urgent update to AppCenter, please be patient 🙏️.
@alainm23 don't worry, man! We all admire your work and understand the problems one has to face when it comes to software development! I'm sure you will find a solution! I was just offering a momentary solution in case the other users didn't know how to fix it.
