Status in curl package in Ubuntu: Confirmed Bug description: Hi! After last updated libcurl3 on libcurl4, system (Kubuntu 18.04 bionic) deleted such applications as: virtualbox-5.2 opera-stable slack-desktop mongodb I really need these applications, I installed them with broken dependencies, but they are deleted after each update. Is it possible to make the dependence of the libcurl3 in libcurl4, and not remove it altogether from system?
