Retropie updates install extremely slowly although Pi is mostly idle

tungsten

Hello,

I'm on a Pi4 and use Retropie 4.7.1 with the image provided from this website.

When I select "Update all installed packages" from the setup menu, this process takes extremely long, but checking with "top", I can see that the Pi is completely idle. So it's definitely not compiling anything.

For example at this step:

It just stays like this without any output for about 5 minutes before moving on.

Then it goes on like this:

So this is just an example to illustrate where it hangs, and this applies to all packages. But there are no meaningful error messages and I really don't know what's actually going on in the background.

Any help would be appreciated :)

Ok, I could solve it. There must have been a problem with IPv6, deactivating it solved the problem as in this thread:

https://retropie.org.uk/forum/topic/28939/updating-broken-connection-time-out/7

Maybe this should be added to the documentation or the FAQ or somewhere as it seems to affect some people.

I deactivated it according to this guide:
