I tried again today, I still get the errorklogg depends on libqt5widgets5 (>= 5.9.5)and if you try installing that you get an error about a broken installSo this sequence of 3 commands works:# 解决方案sudo apt --fix-broken install # takes a while, lots of outputsudo apt install libqt5widgets5 libqt5xml5sudo dpkg -i klogg-20.9.0-r672-Linux.debIt's not the fault of klogg, but of of the 20.04 distribution or Amazon's AMI from which they expect us to install ubuntu 20.04. Anyway this works.
