Questions on howto do as it says in the title.
I currently have 17.12svn11872 installed (from distro).
I've downloaded the binary for codeblocks_20.03_amd64_stable.tar.xz from FossHUB and extracted it's contents.
Am now sitting with the current (older) installed version, a bunch of compressed .deb's, and want to upgrade(or clean)install 20.03.
I cannot find guidelines for upgrading or any clear howto on installing the bunch of compressed .debs.
Can anyone pls tell me how to go about it?
