I have recently migrated to Zorin OS from Win10, I am a very basic user but migrated to Linux and specifically to Zorin because my old laptop had severe lag issues with Windows 10.
After installing Zorin, the laptop seems to have gotten a new life and Zorin is appealing too.
The question: I created a Libre Office Impress presentation yesterday and today morning when I tried to open it, it threw an error that reads:
Could not open LibreOffice Impress.odp
Archive type not supported
The same error occurred when I tried to create a new spreadsheet (Libre Office Calc file).
Can anyone having proficiency help me out to resolve the issue?
