This seems to be a Problem with the Permissions of the Mentioned Directory the Directory owner would be set to root by default kindly switch as a root user or use the command in sudo mode which will help in resolving

CodePudding user response：

you do not have root to access the files. Try sudo apt-get update instead

CodePudding user response：

clearly indicates that the filename is wrong:The file name your are trying to open via command. Also please provide the command you are trying to execute.

Go to the directory cd /etc/apt/sources.list.d/ and check the file name exist . Provide sudo to permit .

Meanwhile check for running apt-get processes: ps -A | grep apt

If multiple process exist then try to kill which is struck by using sudo kill

Clean up the lock files that you are struck with by : sudo rm /var/lib/dpkg/lock sudo dpkg --configure -a sudo rm /var/lib/apt/lists/lock sudo rm /var/cache/apt/archives/lock

Then run sudo apt-get update
