My remotes are the following:

conan-local: some-private-url [Verify SSL: True]
bincrafters_remote: https://api.bintray.com/conan/bincrafters/public-conan [Verify SSL: True]
conan-community: https://api.bintray.com/conan/conan-community/conan [Verify SSL: True]
conan-center: https://api.bintray.com/conan/conan/conan-center [Verify SSL: True]

and the output of conan user is the following

Current user of remote 'conan-local' set to: 'None' (anonymous)
Current user of remote 'bincrafters_remote' set to: 'None' (anonymous)
Current user of remote 'conan-community' set to: 'jjcasmar' [Authenticated]
Current user of remote 'conan-center' set to: 'None' (anonymous)

So, if I am correctly authenticated into conan-community, why am I getting a permission defnied error when trying to install the recipe. Also, I though that for installing recipes there was no need to authenticate so what is happening here?

EDIT: I have also tried to install the recipe without authentication, but in that case it just asks for a username/password. If I try my bintray username and password, it rejects them.

I experienced this issue in 2020 on Ubuntu 18.04, and was able to solve it by upgrading to Conan 1.20.2 via the following terminal commands:

sudo -H pip3 uninstall conan

sudo -H pip3 install conan==1.20.2
