I recently uninstalled LibreOffice to install OpenOffice and experienced no problems in using Open Office. Later, I installed a file preview software known as Sushi. When trying to view .odp files, Sushi stated that it needed additional software to preview those files. I went ahead with the download, and it installed packages relating to Libreoffice which are in conflict with the OpenOffice packages. When I try to install software, I cannot download anything; this is the error message that I get:
Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: libreoffice-core : Depends: libreoffice-common (> 1:220.127.116.11) but it is not installed libreoffice-help-en-us : Depends: libreoffice-l10n-en-us libreoffice-l10n-en-gb : Depends: libreoffice-common but it is not installed libreoffice-l10n-en-za : Depends: libreoffice-common but it is not installed E: Unmet dependencies. Try using -f.
I've tried using -f both before and after the install in terminal as well as unchecking all options in the "other software" section of "software & updates." (getting error messages which I could post here for clarification if asked) I've tried clearing the software cache out using "clean" and "autoclean" as well as purging OpenOffice and the libreoffice-core to no avail.
Any suggestions as to what to do? Everything else on the system works very smoothly. I just can't do updates.
I'm fairly new to Ubuntu and command line, very much a rookie. With that being said, is there a way to uninstall recent updates (as shown in "History" in Software Center)? I have little data on the computer and wouldn't mind wiping it either as a last resort and doing a fresh install. (but I don't know how to while keeping it as a dual boot machine with Win 8)
