installing qt on raspberry pi 4

Question

I'm installing Qt to my raspberry pi-4 for image processing project. I use the commands:

sudo apt update
uname -a
apt-cache search qt5
apt-cache show qt5-default
apt-cache search qtcreator
apt-cache show qtcreator

and

sudo apt-get install qt5-default

it gives error saying that:

E:Unable to fetch some archives,maybe run apt-get update or try with --fix-missing?

How should I fix this error?

Did you try the fix? Can you please edit your post to show the output of the commands? If you use apt rather than apt-get it can give you more info (its better for command line use while apt-get is better in scripts). Start with sudo apt update — user115418, Apr 2, 2020 at 17:31

Just type below command:

$sudo apt-get update --fix-missing

I think it will work for you!
