I've tried everything to fix the error E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?.
I've tried cleaning the apt-get system, using install -f, obviously using fix-missing and update or upgrade.
The output of my sudo apt-get install qtbase5-dev:

I have tried everything I've seen on other questions and other forums but I really don't know how to solve it.
Do you have any idea?
Thank you in advance!
EDIT
Added some terminal outputs
~: dpkg --print-architecture
amd64
And
~: dpkg --print-foreign-architectures
i386
arm64
