Today i have keep getting an annoying error when i try to install some python libraries.
"E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/cache/apt/archives/"
This is the first time i got this error and i don’t have any clue how to solve this. I googled a bit and found the solution after spending almost an hour. I wanted to share with Unixmen readers. Here you go.
Problem:
Here what i did to install to python libraries.
# apt-get install python-twisted

Solution:
If you encounter with the same error, do the following steps.
Run the following command to unlock the apt package managers.
# rm /var/cache/apt/archives/lock
Now update the sources list using command:
# apt-get update
Finally try again to install the packages you want.
# apt-get install python-twisted

Need to get 3,697 kB of archives. After this operation, 16.9 MB of additional disk space will be used. Do you want to continue [Y/n]?
Voila! Now the package manager lock has been released and you’ll be able to install the packages without any issues.
Cheers!
