-bash: cd: /root/Downloads/: Permission denied

As an AI language model, I do not have access to your computer's file system or root privileges to change permissions. However, you can try the following steps to resolve the "Permission denied" error:

1. Check if you have the necessary permissions to access the directory. Use the command `ls -l` to check the permissions of the directory and make sure you have the necessary permissions.

2. If you are not the owner of the directory, try using the `sudo` command to gain root privileges and access the directory. For example, `sudo cd /root/Downloads/`.

3. If you are still unable to access the directory, try changing the permissions of the directory using the `chmod` command. For example, `sudo chmod 777 /root/Downloads/` gives all users full access to the directory.

Note: Be cautious when changing file permissions, as it can affect the security and stability of your system.
