问题:
Could not open file /var/lib/apt/lists/partial/security.ubuntu.com_ubuntu_dists_xenial-security_restricted_dep11_Components-amd64.yml.gz - open (13: Permission denied) [IP: 91.189.91.26 80]
解释:
/var/lib/apt/lists folder messed things up
解决:
sudo -i
apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update
This will rename your "list" folder to "list.old" for backup purposes and then rebuild.
If you did an error free "apt-get update" then yes, the "list.old" folder is corrupted and can be deleted. List.old served its purpose as a backup (the original) in-case something went wrong.
