As you can observe in the picture "opera-stable" and "uget" have a similar dependency called "libcurl" but they differ in the version.
When I install opera, uget stops working, and the same happens backwards.
How can I have both installed at the same time?
Is there a global method for similar issues and dependencies?

  • Libcurl3 was dropped from Ubuntu after 18.04 in favor of Libcurl4. It is generally unwise to install older browsers -- they tend to be vulnerable. – user535733 Feb 14 at 18:21
  • I have a 32bit operating system installed , So I had to use this out-dated version .I also tried using snap , but snap offers only the latest version of opera which is not supported by i686 architecture . So I had to download .deb installation file of opera45.0.2 (the latest version for 32 bit os) and this conflict is shappened – Master Pythoner Feb 14 at 18:25
  • Libcurl3 and libcurl4 are mutually incompatible. Only one can be installed (by apt) at a time. There is no deb-based workaround. There are several clever and complex non-deb solutions, if you have the skills to create a container or install from source code. – user535733 Feb 14 at 19:37
