I have tried the command “sudo do-release-upgrade", and it wanted me to do an upgrade first. I did one through the software updater. After an initial upgrade, it reported “all packages are up to date.”
Do-release-upgrade still wanted me to update my packages first. With the package updater, I got the names of three packages that were “blocked from update”. On the command line, this is what I got when I tried to remove the “blocked” packages: Script started on Wed 16 Jan 2019 07:00:48 AM EST paul@rivendell: ~paul rivendell~ $ sudo do-release-upgrade [sudo] password for paul: Checking for a new Ubuntu release Please install all available updates for your release before upgrading. paul@rivendell: ~paul rivendell~ $ apt-get remove python-laditools-1.1..

Then it might be easier to copy and paste any error messages on an email to the list. There are places you can retrieve the apt logs, but you probably won't need to if the error is obvious to us here.

I cliked the button that said “Update …”, and all the window does is disappear, with no further response. I have tried this several times. I have had what I call minor problems with the software updater in the past, where it would say that update has failed for some unknown reason, I dutifully click “send report”, but in fact, the system was updated, but for a few Python packages which look old, and “blocked” from update. It appears as if the “minor” problems may be causing update to fail. I cannot find any system log that tells me what crashed, although I managed to read one of my reports that Software Updater would send, and I remember seeing a message that apt had crashed (I recall it was apt and not aptd). I did not see information there that gave a reason. Paul King
