Solve the problem: E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)

Does the following situation occur when using ubuntu, especially when installing or updating: E: Could not get lock /var/lib/dpkg/lock – open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? As a result, it cannot proceed?

The simplest and most direct way:

sudo rm /var/lib/apt/lists/lock

sudo rm /var/cache/apt/archives/lock

In most cases, the cause of the problem is that other programs such as system automatic updates, Synaptic, etc. are using the apt-get process, so the solution is to close this process.

The details are as follows:

1. ps-aux finds out the PID of the apt-get process, which is usually a four-digit number.

2. Use sudo kill PID code to kill the process

3. Use sudo apt-get update and sudo apt-get dist-upgrade to upgrade.

Method 1:

Execute sudo dpkg –configure -a

Method 2 (can be used for personal testing):

sudo rm /var/lib/apt/lists/lock

Method 3:

1. ps-aux finds out the PID of the apt-get process,

2. Use sudo kill PID code to kill the process (I always find the process with the word apt and kill it)

The actual cause of the error: It is caused by referencing the wrong link.

Solution (just delete these references):

After deletion, execute sudo apt-get update, and then you can install the software normally.
