apt获取节点上的权限错误。js设置

我正在尝试安装node。ubuntu上的js 7。运行命令时

curl -sL https://deb.nodesource.com/setup_7.x | bash -

sudo curl -sL https://deb.nodesource.com/setup_7.x | bash -

我得到以下错误:

## Installing the NodeSource Node.js v7.x repo...


## Populating apt-get cache...

+ apt-get update
Reading package lists... Done
W: chmod 0700 of directory /var/lib/apt/lists/partial failed - SetupAPTPartialDirectory (1: Operation not permitted)
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/srcpkgcache.bin - RemoveCaches (13: Permission denied)
Error executing command, exiting

我还跑过:

apt-get update

sudo apt-get update 没有错误,但在运行前两个命令时再次出现错误。

我已经试过了 autoremove purge 和 upgrade 但问题仍然存在。 任何帮助都将不胜感激
