Hi, I have a problem installing k6 on Ubuntu 25.04. When I run:
sudo gpg -k
sudo gpg --no-default-keyring --keyring /usr/share/keyrings/k6-archive-keyring.gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys C5AD17C747E3415A3642D57D77C6C491D6AC1D69
echo "deb [signed-by=/usr/share/keyrings/k6-archive-keyring.gpg] https://dl.k6.io/deb stable main" | sudo tee /etc/apt/sources.list.d/k6.list
sudo apt-get update
sudo apt-get install k6
I get:
gpg: key 77C6C491D6AC1D69: "k6.io (key for signing binaries) <security@k6.io>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1
