I managed to make it work with slimjet after using an idea from: https://github.com/getinsomnia/insomnia/issues/805
*Here's my dirty "workaround".* Short version: modify the .deb package to control for libcurl version 3 *OR 4*. Detailed version: in a terminal, change directory to the folder containing slimjet's .deb package, then: sudo mkdir tmp sudo dpkg-deb -R slimjet_amd64.deb tmp # now edit the "control" file to replace "libcurl3" by "libcurl3|libcurl4", then save sudo dpkg-deb -b tmp slimjet_amd64_fixed.deb Finally, execute the new "slimjet_amd64_fixed.deb" package to install slimjet. Hope this solution will suffice until the real problem is fixed. ** Bug watch added: github.com/getinsomnia/insomnia/issues #805 https://github.com/getinsomnia/insomnia/issues/805 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to curl in Ubuntu. https://bugs.launchpad.net/bugs/1754294 Title: After last updated libcurl3 on libcurl4, some apps are removed. 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 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?
