I used Ubuntu 19.04 and Libreoffie 6.24 that attaced to ubuntu
Today, I wanted to use last update version (6.30).
So, I removed the 6.24 version type next 3 command.
sudo apt-get remove --purge libreoffice*
sudo apt-get clean
sudo apt-get autoremove
And installed 6.30 version from Ubuntu Software Center.
All the other functions work well but the fomula objects are crash with weired symbol.
How can I fix it?
