This question already has an answer here:
Consider a situation like this:
I am going to install Ubuntu on an UEFI system (dual boot with Windows) where
I need to install
boot-repair. When I run
sudo apt-get update it will
update cache for all the repos. I need to update only a particular
yannubuntu/boot- repair) to install
Many times I had to update all the repos when I think updating a single
ppa is enough.
- Is there any problem/harm if I update only one repo? Can it affect the software installation in any way?
- If the answer is
Nothen how could I update a particular repo?
