Hot to fix apt-get “The following signatures were invalid: KEYEXPIRED”

If you are trying to run apt-get update on your ubuntu machine and seeing the error "The following signatures were invalid: KEYEXPIRED" you have come to the right place. The key expired error occurs when one or more existing key on your ubuntu machine has expired which is hindering the update. To fix this issue, you need to renew these keys. Here are the steps to renew an expired key
  • Find the expired Key: Run the below command which will list all the expired keys on your ubuntu machine. Make a note of all the keys. 
    • sudo apt-key list | grep -A 1 expired
  • Renew the expired Key: Take the keys from the previous command output and replace the <KEY_ID> in te below command with that. Execute this command to renew the expired key.
    • sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys <KEY_ID>
  • Run apt-get update: Now that you have renewed all the expired key you can now try running apt-get update again and it should work perfectly this time.
    • sudo apt-get update
Refer to this screenshot for more details.


Hope it was helpful...!!!

Get rid of "Timed out receiving message from renderer"

Get rid of "Timed out receiving message from renderer" Message Well, if you using selenium web driver to automate your web flows you must be really annoyed by now with the console log [SEVERE]: Timed out receiving message from renderer: 0.100 This not only gives us a false impression of some error happening during the run but also makes it difficult to go over the console logs. Luckily, we can make use of the silent output mode in chrome to get rid of these messages. To do so we need to set the silentOutput parameter to true in System property as follows. System.setProperty("webdriver.chrome.silentOutput", "true"); and voila...no more annoying timeout message.   If you don't want to use setting the system property way for any reason, there is another way for you to achieve this. You can make use of ChromeDriverService builder to build it with " withSilent " set to true in the code as below.   ChromeDriverService.Builder bu...

Launching Selenium Grid: Download the latest version of Selenium Standalone Server from here . Open command prompt and cd to the path where you downloaded the selenium server jar file from Step 1. Ex. " cd ~/Downloads " Next we need to run the below command to start the selenium hub   (replace selenium-server-standalone-3.9.0.jar with the latest selenium server file name you downloaded) java -jar selenium-server-standalone-3.9.0.jar -role hub -port 4444 Check for the success message " Selenium Grid hub is up and running " in the console Open browser and navigate to " http://localhost:4444/grid/console " to check if the grid is up and running. Tips: Instead of doing cd to the selenium server file location and then running the command we can directly run the command by giving the absolute path of the selenium server jar file in the command java -jar /home/nishant/Downloads/selenium-server-standalone-3.9.0.jar -role hub...
