Q:

Can't open any Libre Office docs in 12.04

This error message pops up when opening a document in LibreOffice:
LibreOffice 3.5
Read-Error.
An unknown error has occurred.

I can, however, open a fresh new document. This is obviously not desirable behaviour.
EDIT: I tried opening a Calc doc which I used in my 11.04 installation (which is now 12.04). The documents are as they always were, in my Documents folder. Impress files seem to open fine. I've not yet tried a Writer file yet, as I don't use them too often.
What is the problem?

A:

I have the same problem. Run command as it explained above and i got this error message:
krator@laptop:~/Documents$ libreoffice --writer myFile.odt 
[Java framework] Error in function createSettingsDocument (elements.cxx).
javaldx failed! 
Warning: failed to read path from javaldx
terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException'
krator@laptop:~/Documents$

Any fix for this issue?

Ok, I found the answer to this issue. Here is solution:
Fixing Java Framework Error
You may get the following error when you try to run OpenOffice.
[Java framework] Error in function createSettingsDocument (elements.cxx).
javaldx failed!

If so, give yourself ownership of ~/.config/ like so:
sudo chown -vR username:users ~/.config

A:

Run this command and your problem should be solved:
sudo apt-get install libreoffice
