How to fix apt timing out on a Raspberry Pi
November 6th, 2024
On some corporate networks I’ve run into a brick wall when using apt update
on a Raspberry Pi. The first couple of repositories connect successfully. Then it usually gets up to archive.raspberrypi.com
and hangs and times out.
Apt defaults to IPv6 when it is available, and in some cases it just does not seem to play nicely. The solution - force IPv4 instead.
You can do this via the -o
flag when running the command:
sudo apt -o Acquire::ForceIPv4=true update
Or you can edit the apt configuration and add a line to make IPv4 permanent:
sudo nano /etc/apt/apt.conf.d/99force-ipv4
Add this line:
Acquire::ForceIPv4 "true";
