I hope you are running the commands as root, but anyway even if logged as 'user' you should be able to access /etc/apt directory. This is from my device: Code: /etc $ ls -ald /etc/apt drwxr-xr-x 6 root root 4096 Apr 2 21:08 /etc/apt How does that look in your case?
/etc $ ls -ald /etc/apt drwxr-xr-x 6 root root 4096 Apr 2 21:08 /etc/apt
