Hello, When I was in the process of installing the latest version of ubuntu 20.04.1 LTS , the process crashed. I restarted my system and then when I booted Ubuntu, it went fine. I was also able to install all updates and upgrades, but when I typed ''apt update" , it showed ''Reading package lists... Done E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied) E: Unable to lock directory /var/lib/apt/lists/ W: Problem unlinking the file /var/cache/apt/pkgcache.bin - RemoveCaches (13: Permission denied) W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - RemoveCaches (13: Permission denied)'' . How can I give permission to this directory?

When I type "apt upgrade" in terminal, it showed, E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

Please help,
Thank you

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

FYI: You need elevated privileges to run package tools, so the command needed to update your software lists is

`sudo apt update`

and to install upgraded packages

`sudo apt upgrade`

(or `sudo apt full-upgrade` to install all packages)

The `sudo` elevates your privileges.

I'm marking this as 'incomplete' as I don't see any problem, if you believe I'm in error, please leave a message explaining why, and you can change the status to "New".
