The command sudo apt-get update does not install any available software update. Instead it will update the locally cached information about the available software packages by querying the configured software repositories.
So the steps to update the software libreoffice would be:
sudo apt-get update
sudo apt-get upgrade libreoffice
I hope you are a little familiar with Terminal !!
ctrl+alt+t....will bring up a terminal screen....or yu can open the menu....and just type .. terminal ....
after you copy and paste the first comman above (sudo apt-get update) ...you will be asked for your password....the letters/numbers etc will not show...just type then in anyway and hit enter The screen will go through a great jumble of gobbledegook......and then it will settle down...looking much the same as it did when yu first opened the terminal.
Then....copy and paste the second command (sudo apt-get upgrade libreoffice).....it may or may not ask for your password again....I think not...but if it does then just type it in again.
Let us know the outcome
Hi Condobloke, excuse my late response. Some visitors popped over and then it was late, went to bed. So I tried the command line you gave me and it didn't work. It was still version 5. So I did a new install, which also didn't update it either. Being a newbie, thought I'd try. However, to get to the point, did some searching and found the following from
https://forums.linuxmint.com/viewtopic.php?t=269343 worked a treat.
sudo apt-get remove libreoffice-core
sudo add-apt-repository ppa:libreoffice/ppa
sudo apt-get update
sudo apt-get install libreoffice
I now have 6 on my 18.3 Linuxmint. I just wanted to update my status and let you know and anyone else that might find themselves with the same problem.
Thanks again for your time Condobloke and all the best.
