I installed Ubuntu 18.04(LTS) just yesterday. I am trying to install packages using sudo apt-get install , but I am getting the below error (this example is for 'make') :
Package make is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'make' has no installation candidate
I tried googling it, found something related to mirrors and sources, but not able to figure out what to do. Please help.
sudo apt update && sudo apt upgrade
without errors?
