I'm trying to install Qt Creator to my Raspberry Pi 3 for a GUI project. However when I use the command
sudo apt-get install qt5-default
it gives an error saying that:
E:Unable to fetch some archives,maybe run apt-get update or try with --fix-missing?
As I considered the advice of my raspberry pi I tried the command
sudo apt-get update. However I got errors again saying
Some index files failed to download. They have been ignored, or old ones used instead.
Apparently I am doing something wrong and any help will be appreciated.
Edit for clearance: Normally I was able to get updates without any errors. However after trying to install Qt it started giving errors as I tried to update.
