Solved
Could not determine GDB version, launch failed on Ubuntu 23.10 : libncurses6
libncurses5 and libtinfo5 were replaced by libncurses6 and libtinfo6 in Ubuntu 23.10.
No Debug possible anymore inside IDE.
Update not yet available.
Is it safe to replace version 11.3 of the toolchain with i.e. 13.2?
Will it work to overwrite the plugins/...gnu-tools... folder?
Thanking you in advance.
