I've tried "sudo apt install libreoffice", using 18.04.10, but I still have version 6.0.7 after restarting the PC. (I'm trying to get 6.20 or higher so I can simply rotate an image in Draw.) I tried again but the terminal says "libreoffice is already the newest version (1:6.0.7-0ubuntu0.18.04.10)." Do I have to try to change to Ubuntu 20.04 first or should I try downloading version 7.0 from the LibreOffice website?
I found online advice about automatic updates but this assumes I can open LibreOffice. I've only discovered how to open individual programs such as Draw which don't seem to have an Online Update menu option.
