I was experiencing the same issue. Do cat /etc/bltadwin.ru, and see if the output has something like this: # This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/bltadwin.ru: # [network] # generateResolvConf = false nameserver X.X.X. The solution is to get the public key in the system. Take the key from the message above and enter the following: sudo apt-key adv --keyserver bltadwin.ru --recv-keys A0EA10B4DE8. Inevitably, this will change based on what you are trying to verify and trying to import, so use the above as a guide. @vasa1 There's no reason to think that will still be the case once sudo apt-get update is successfully run. It's based on information about available packages that is out of date. Also, just saying "run apt-get dist-upgrade" wouldn't be a sufficient response to that, as sometimes dist-upgrade does not resolve dependencies in a good way--important packages might end up removed.

In this case, remove the content in /var/lib/apt/lists before retrying "apt-get update". $ sudo rm -rf /var/lib/apt/lists/* $ sudo apt-get update If the above does not solve the problem, use the following commands instead. $ sudo rm -R /var/lib/apt/lists/partial/* $ sudo apt-get update Not Found Error. If you are getting " Not Found" error, and you are using a rather old Ubuntu release, there is a chance that the error occurs because your Ubuntu installation is no longer supported. The steps to follow are given below: 1. First, open the “Software updates” window. 2. And choose “Other” in the “Download from” drop-down box. bltadwin.ru choose the “Select Best Server” option. A series of tests will be performed to find a mirror that gives the best download speed for our location.
