Ubuntu – LibreOffice Base not opening in 14.04

First search for open libreoffice files:

ps aux | grep libre

For example the output of mine is:

hadi  21426  0.1  0.0 205328  3468 ?        Sl   14:17   0:00 /usr/lib/libreoffice/program/oosplash --writer
hadi  21445  9.8  0.7 1269272 179872 ?      Sl   14:17   0:01 /usr/lib/libreoffice/program/soffice.bin --writer --splash-pipe=6

then

sudo kill -9 ID

the ID is the second number for (soffice.bin) not for oosplash

so in my example:

sudo kill -9 21445

You need professional Ok:

ps aux | grep -i office | awk {'print $2'} | xargs kill -9

hope this is professional in your evaluation!!

or more minified command

kill -9 `pgrep -lf soffice.bin | awk {'print $1'}`

or more minified minified minified command

pkill soffice.bin

EDIT:

All libreoffice open files take the same PID, for that you can't just kill writer and keep impess for example.

And to prove my point of view the recovery tool in office is unique for all files. What i mean if you close a writer in imporper way and then open an impress for example then impress will request you to recovery the writer file and it did so and this proves my answer

For those of you who haven't resorted to the PPA and just want to install the missing pieces, Open Software Center, type libreoffice in the search box and select the missing components and install them. In my case, base is the only one I don't have installed. Example below:

If you've already unnecessarily installed the PPA you can revert to the distribution version vis the use of ppa-purge

ppa-purge provides a bash shell script capable of automatically down‐
       grading all packages in a given PPA back to the ubuntu versions.

       You  have  to  run it using root privileges

For further details in it's use please see the man page with the command

man ppa-purge
