Public bug reported: There is a problem during the upgrade to 20.04. It says "unofficial software packages not provide by Ubuntu.....remove software. I have removed problem with dependencies in "other software and synaptic". I have removed old ppa in terminal. I try again but there is always the same problem. The other option, looking in the log files, I do not know where to find the "var" folder. Thank you for taking your time reading this.
