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.

Here is a working way to install Qt5. For Qt5 there is no need for dev-tools. So this command is not relevant:

sudo apt-get install qt4-dev-tools

The two commands needed to install Qt5 fully are:

  1. sudo apt-get install qt5-default (installs Qt version 5.7.1)
  2. sudo apt-get install qtcreator

Hope this helps.

Not particularly sure why you are trying to install that package, the App Note for installing Qt Creator on Raspberry Pi says to install 

sudo apt-get install qt4-dev-tools

and

sudo apt-get install qtcreator

Some extra packages are also listed.

I personally keep Qt Creator on my PC which can compile programs a lot faster during development and then follow their Build Guide so I can compile it naively on a releasable version.
