Comment 61 for bug 1754294

At first I was annoyed by this strange choice by Cannonical. I mainly do not understand why libcurl3 and libcurl4 cannot be installed at the same time as is usual with libraries of different major version.
Then I got to accept that the problem actually needs to be fixed in the dependent programs - they need to switch from libcurl3 to libcurl4 which is now the default in Ubuntu 18.04. VirtualBox and Slack already have and I'm sure the rest will follow quickly. If not complain to them.
I expect this "issue" will not be fixed.
