I was trying to install MongoDb on Ubuntu 17.10 but i couldnt or there were some errors so I decided uninstall everything and reinstall fresh. So i did some purge commands that i found on the net and after doing that now if I do: sudo apt update
i get the following messages
sudo apt update
E: Malformed entry 1 in list file /etc/apt/sources.list.d/MongoDB.list (Suite)
E: Malformed entry 1 in list file /etc/apt/sources.list.d/mongodb.list (Suite)
E: The list of sources could not be read.
In this case, as you dont have a specific line wrong in the file, better delete the file MongoDB.list and add again the respective PPA. Try it:
sudo rm /etc/apt/sources.list.d/MongoDb.list
Add again the PPA from MongoDb
Now is time to update by running
sudo apt-get update
