This question already has an answer here:
I have seen the following question, however it doesn't solve my problem:
I can't update my Ubuntu 12.04! I get the following error after running
sudo apt-get update:
E:GPG error: http://http precise/ Release: The following signatures were invalid: NODATA 1 NODATA 2
Following is the content of
###### Ubuntu Main Repos deb http://mirror.informatik.uni-mannheim.de/pub/linux/distributions/ubuntu/ pr$ deb-src http://mirror.informatik.uni-mannheim.de/pub/linux/distributions/ubuntu$ 3rd Party Binary Repos #### Google Chrome Browser - http://www.google.com/linuxrepositories/ ## Run this command: wget -q https://dl-ssl.google.com/linux/linux_signing_key.$ deb http://dl.google.com/linux/chrome/deb/ stable main
What I have tried so far:
- I have tried changing sources and made a new, clean
/etc/apt/sources.listfile. But the issue still persists.
sudo rm /var/lib/apt/lists/* -vfdoesn't help either.
How do I resolve the issue?
