View installed software
1. Check the help of dpkg.

2. First list the libreoffice related software and see which ones have been installed. The command is: dpkg -l libreoffice*
3, Among them, un, ii, rc, etc. are Desired and Status
Desired=Unknown/Install/Remove/Purge/Hold
Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
