OK looks good. If you run:
sudo do-release-upgrade
Does it upgrade to 16.04 ok?
You need to upgrade to 16.04 first and then to 18.04 from that (LTS to LTS upgrades are supported) you cannot leapfrog versions so you cannot go from 15.10 to 18.04 without wiping the current installation off and doing a clean install of Bionic from USB / CD

thank you very much for your help
I upgrated to 16.04LTS online, it takes about 1 hour, and then I upgrated to 18.04LTS online, it takes about 2 hours
now the system is working with 18.04LTS with libreoffice

from terminal:
sudo do-release-upgrade
and I had an error “the required dependency 'apt (>= 1.0.10.2ubuntu2)' is not installed”
I downloaded the file:
http://
and run it
Then I run
sudo apt-get update
sudo do-release-upgrade
and I installed 16.04
After reboot I run again
sudo do-release-upgrade
and I installed 18.04
thank you for your help
