I've having problem installing vim on my Ubuntu. After running sudo apt-get install vim, I get the following error message:
Ign:1 http://ca.archive.ubuntu.com/ubuntu focal-updates/main amd64 vim-runtime all 2:8.1.2269-1ubuntu5.7

E: Unable to fetch some archives, try running apt-get update or apt-get --fix-missing.
While I tried running apt-get update, it gives me this error message:
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)
Can anyone help me to look at what is the problem? I would assume it is a permission issue but not sure how to fix it. Thanks.
