How we fix Docker error processing tar file
Let’s move to the solution part of this error. Here are the cases where we resolved this error for our customers.
1. Remove unused images
Recently, one of our customers approached us with the same error. He was trying to clear the space from his device and ran into the below error.
ERROR: Error processing tar file(exit status 1): unexpected EOF.
Now, let’s see how our Support Engineers fix this error for our customers.
First, we used a built-in command to remove unused images (Version 1.13+)
docker image prune
Then we ran the below command to stop the Docker.
systemctl stop docker
After that, we backed up the docker folder /var/lib/docker and removed it by running the below command
NOTE: This will remove images, containers, volumes, … make sure you back it up first.
rm -rf /var/lib/docker
Once this is done, we started the Docker service by running the below command.
systemctl start docker
This, fixed the error.
2. Permission issue
In a few cases, we saw that the files owned by root in the directory having permission issues. Providing the files proper permissions fixed the issue. For that, we used the below command.
chown -R <username>:<group> /var/lib/docker/tmp
