I'm trying to upgrade my desktop from ubuntu 16.04 to 18.04.
(I regret not having upgraded it earlier before the ubuntu 16.04 EOL arrived. Two weeks ago I have upgraded two 16.04 notebooks to 18.04 though eventhough it was after the EOL, at that time there was just small problems I could solve).
sudo apt update but I'm getting the error below during
apt upgrade after that.

The command python is linked to python2.7 and python3 is linked to python3.5 using alternative system.(update-alternatives). What can I do next?
I saw somewhere I have to reinstall opca-client so did this,
ckim@chan-ubuntu:~$ sudo pip3 install --upgrade opcua-client
and then I saw a warning about pip version, so I did
sudo pip install --upgrade pip
and then sudo pip3 install --upgrade opcua-client but now see this error below :
