libcurl4 Conflicts: libcurl3 - prevents install of 3rd party apps like slack-desktop

Bug #1754686 reported by Nathaniel W. Turner
This bug affects 52 people
Affects Status Importance Assigned to Milestone
curl (Ubuntu)

Bug Description

Updating the curl package pulls in libcurl4, which for some reason forces libcurl3 to be removed. This prevents 3rd party apps that still build against libcurl3 from being installed. Isn't there a more graceful way to effect the transition from libcurl3 to libcurl4?

This also affects the installation of popular 3rd party application Spotify:

I wonder, Debian still has libcurl3 versioned library/symbols in their 'unstable' repo, their libcurl4 is only in experimental yet. I understand that with the perspective of LTS-support upgrading to libcurl4 can be a good move, from security perspective, but there should be a graceful upgrade path and if possible some kind of legacy support of packages that were built using libcurl3 (maybe the libcurl3 libs can also be part of the libcurl4-package and that in its dpkg control it also 'provides' libcurl3?

I have a problem with the library too. My conflict is with spotify-client and hosty.
Spotify-client requires libcurl3, and installing it uninstalls curl, which is required to run hosty.

I am also affected by this. both Virtualbox and Slack need 3, and Cairo and others need 4.

what is funny is that chrome doesn't have an issue if you use it for slack. I would prefer to have the package install of slack-desktop, but in the interim I have just created a 'desktop app' of slack for now.

I had to uninstall Virtualbox as well.

As is it third party/proprietary softwares you should report bugs against their repo instead of here.

* Spotify yet fix it :
* skypeforlinux works
* virtualbox-5.2 5.2.10-122088 works
* insomnia 5.16.0 works
* and so on

The other will follow. If you want slack-desktop works ask to Slack on their bug tracker.

Would love a way to install libcurl3 alongside libcurl4. Right now vpn unlimited doesn't work either because it depends on libcurl3

All BOINC packages depend on libcurl3. Ukuu wanted to install libcurl4 and remove libcurl3.
