Recently (2-3 weeks ago), a message started showing up after clicking on the Impress shortcut. Message is the following (tr. from French): "Object cannot be accessed because user's rights aren't sufficient". But I can still open my already existing .odp files with Impress, modify and save them. I just cannot create a new one from the shortcut. Other Office softwares are starting without troubles from the shortcuts. So it doesn't stop me from using the software but it would be easier if I could use the shortcut again. Any idea how I could solve this issue?
Edit: I'm on Ubuntu 18.04.1 and I've also a windows partition mounted on my computer.
2nd Edit: Even when logged as root (which has got the permission on libreoffice impress) with the
sudo su command, I cannot open the application directly.
Thanks in advance and have a great day!
