Instalé Anaconda en el servidor Ubuntu 18.04 recientemente y hoy, cuando instalé un paquete nuevo, apareció una advertencia:
==> WARNING: A newer version of conda exists. <==
current version: 4.6.14
latest version: 4.7.5
Please update conda by running
$ conda update -n base -c defaults conda
Entonces, ejecuté el comando mencionado anteriormente (dentro de mi r_enventorno si eso importa) y todo parecía estar bien:
(r_env) user@server:~$ conda update -n base -c defaults conda

Intenté bajar condaa 4.6.14 sin éxito; aparece el mismo error. ¿Existe alguna posibilidad de solucionar el problema sin reinstalar Anaconda?
