amd64v3 now available in Ubuntu 25.10

jak włączyć: jeśli twój procesor obsługuje x86-64-v3 możesz dodać linię APT::Architecture-Variants "amd64v3"; w pliku /etc/apt/apt.conf.d/99enable-amd64v3, potem apt update i apt upgrade.

Try it out

The vast majority of cloud instance types and machines manufactured within the last ten years will support x86-64-v3, and you can check for support on a machine like so:

$ ld.so --help | grep '\-v[0-9]'
x86-64-v4 (supported, searched)
x86-64-v3 (supported, searched)
x86-64-v2 (supported, searched)

If your machine is supported, and you’d like to try out the new packages, you can opt-in to the x86-64-v3-enabled packages. First, install the latest version of dpkg:

$ sudo apt update
$ sudo apt install dpkg

Then enable amd64v3 and update the packages, like so:

echo 'APT::Architecture-Variants "amd64v3";' | sudo tee /etc/apt/apt.conf.d/99enable-amd64v3
sudo apt update
sudo apt upgrade

Note that apt may print that it is “downgrading” these packages – this is just a cosmetic thing and will be fixed in 26.04 as well.
