I need php7.2-curl. But on Debian 10 apt says that it cannot be installed due to a dependency with libcurl3. But libcurl3 cannot be installed (it gives me no reason).

Must I rollback to Debian 9.9?

I already tried to switch to PHP 7.3, but even php7.3-curl depends on libcurl3!


If you want to install PHP 7.2, you’ll probably have to revert to Debian 9, yes. The libcurl transition is a rather complex one and it’s impossible to mix and match libcurl3 and libcurl4-based packages; since Debian 10 uses libcurl4, you need to use packages depending on that. (Ondrej may well provide Debian 10-compatible PHP 7.2 packages at some point, I don’t know what the plans are.)

On Debian 10, you should be able to install PHP 7.3, php7.3-curl depends on libcurl4. If you can’t, you’ve probably got conflicting repositories in your configuration; make sure you only attempt to install PHP packages from Debian itself.

  • Sorry to say that even php7.3 depends on libcurl3... But thanks, I rollbacked to debian 9.9 – realtebo Jul 12 at 14:53

    Did you follow the link? php7.3 in Debian 10 most definitely does not depend on libcurl3. I have it installed on Debian 10 with no external repositories and it works fine. – Stephen Kitt Jul 12 at 14:56
  • I don not know why. My php7.3-curl needs libcurl3. I just downloaded official iso and retried on a clean vm. Sorry to says that. I read that for Debian the php7.x packages have been rebuild to allow both libcurl3 and 4. But i cannot see this relaxed config in the package – realtebo Jul 13 at 17:05
  • You installed from a Debian 10 ISO, then without configuring any extra repositories, you installed php7.3-curl, and it failed because it couldn’t find libcurl3? – Stephen Kitt Jul 13 at 17:16
  • Could you edit your question to show the output of apt policy php7.3-curl? – Stephen Kitt Jul 13 at 17:20
