Hello list, it looks to me that old and new packages have different dependencies. If you're *not* using pillar or phratch, and have problems updating the pharo packages, please execute dpkg -l | grep -i pharo | awk ' { print $2 } ' | xargs sudo apt-get -y purge ; sudo apt-get update && sudo apt-get install pharo-launcher "dpkg -l | grep -i pharo | awk ' { print $2 } '" will list all installed pharo-packages, xargs will give that result to apt-get for the packages to be purged (that is, remove all their data and metadata - the images that you have in your home directory will NOT be affected). Kind regards, Markus
