我在哪里可以找到 Linux ubuntu 中的 kernel.config 文件？

Question

Im copying my kernel config file from an existing system to the kernel tree, and I entered this command: "/boot/config$(uname -r)" Yet I got "bash: /boot/config-5.15.0-46-generic: Permission denied" Does anyone know why its saying permission denied and how to fix? I am using virtual box ubuntu linux O_o

As @Tsyvarev mentioned in comments it is possible that you're trying to execute file, that have no exec permissions:

$ ls -l /boot
...
-rw-r--r-- 1 root root    217414 Aug 20  2021 config-5.4.0-rc1+
...

Try to run: cat /boot/config-$(uname -r) to read the config file for currently running kernel.
