Hello,
So my 17.12 version comes up because it finds it in /usr/local/bin but it appears version 20 binary for buster was installed to /usr/bin which I tried to run directly but get:
/usr/bin/codeblocks: symbol lookup error: /usr/bin/codeblocks: undefined symbol: cbEVT_DEBUGGER_UPDATED
How do I get around this problem?
