The reason they conflict, is that both bundle libcurl.so.3 and libcurl.so.4, which are in fact just symlinks to the actual library.
The best would be to release a new version of libcurl3 that does NOT have a libcurl.so.4 symlink, ONLY the libcurl.so.3 one. And then provide a version of libcurl4 that ONLY has libcurl.so.4, and states that it only conflicts with the libcurl3 versions without the change above. @Brian Murray would it be possible to provide such a solution, to allow graceful upgrades? otherwise I'd expect a lot of similar reports when users upgrade to Bionic, with popular applications like Spotify depending on libcurl3, and that Debian still uses the libcurl3 in their repositories, only their 'experimental' has switched to the libcurl4 naming. -- 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: Invalid 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?
