I just installed Anaconda on Linux. When trying to open spyder (either from navigator or terminal), it does not work. I get the following error when I try to open it in term
I saw issue on brand new Fedora with new anaconda installation. Just updating the spyder to latest version (in my case 3.3.1) fixed it, without anything else.
(BTW: You can do this even from anaconda navigator itself, just look after the wheel within each application panel in the right corner).
Would recommend to fix anything stepwise, start with upgrading to the latest spyder and if this doesn't work, try the other stuff.
