Thanks for the tip, but this operation causes a problem about “yum”.

“yum” command doesn’t working after switching python2.7 to python3.6.

OS: CentOS 7.

Hello

Thanks for the tip

But i get an error when i switch python and try to restart an certain program:

Error:
TabError: inconsistent use of tabs and spaces in indentation

If i get back on the old python … everything works as expected.

best regards john

thanks, very helpful. question: i’m trying to back up all of my current update-alternatives. i understand that it sets a bunch of symbolic links, but is there a single file storing all of my choices? my goal would be to use that file on a clean install so that I didn’t have to re-configure them all. or would the best alternative would be to simply create a script with all of my update-alternatives and run it during my new install?
