gdb not working on Ubuntu 22.04 is a well known issue.
[This topic](community.arm.com/.../gcc-arm-11-2-2022-02-x86_64-arm-none-eabi-gdb-fails-on-ubuntu) is focused on gcc-arm-11.2-2022.02-x86_64-arm-none-eabi where gdb doesn'tt work for some missing dependencies.
[The solution](https://community.arm.com/support-forums/f/compilers-and-libraries-forum/52805/gcc-arm-11-2-2022-02-x86_64-arm-none-eabi-gdb-fails-on-ubuntu/178088#178088) said that next release would have a better compatiblity with newer Linux distros.
And so I downloaded the new arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi.
gdb doesn't work, but now the error message from`gdb --version`is different:

This seems related to [this bug](https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1992947)
Is there any workaround?
Apologies for the delay in responding to you on this. I have referred this internally, and hope someone will have a response for you soon.
