Good evening!

I want to create a bibliography for a thesis but I can't download the related Libreoffice tool because the necessary package is untrusted for my computer. Each time I try I get the following error message:

libreoffice-base libreoffice-base-drivers libreoffice-sdbc-firebird libreoffice-sdbc-hsqldb 

Here is a pic of the situation:

Can you help me download it or find an alternative solution?

I found the answer adapting thanks to saji89's one on how to install untrusted package

sudo apt-get clean

Based on the errors you pasted in the comments section of my previous answer, I have another possible solution:

sudo apt-get clean
sudo apt-get update

I don't know why it worked but I was then able to install the tool!
