> Is it not possible to install and run python 3.8 on RHEL 7?
You have a few options, none really good. 1) build from source 2) a RPM from outside of RHEL; this means you don’t have support and must trust a different third party (not managed by python or RedHat) 3) you use SCL which means every time you want to touch CQLSH you have to remember to enable it (as its per-bash session) These 3 options don’t really work for most deployments > On Mar 11, 2024, at 1:12 PM, Brad <bscho...@gmail.com> wrote: > > RHEL 7 will reach the end of maintenance on June 30th, 2024 (extended > lifecycle support is an option). > > Is it not possible to install and run python 3.8 on RHEL 7?
