Error on install Ubuntu 22.04

[VecH]

All packages are updated Installed according to the instructions, with a couple of changes, but did not affect installation and operation. I was running as root, so I skipped sudo My installation steps:

apt install -y software-properties-common python3-launchpadlib gnupg2 linux-headers-generic
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 57290828
apt-key export 57290828 | sudo gpg --dearmour -o /etc/apt/trusted.gpg.d/amneziawg.gpg
apt-key --keyring /etc/apt/trusted.gpg del 57290828
echo "deb https://ppa.launchpadcontent.net/amnezia/ppa/ubuntu jammy main" | tee -a /etc/apt/sources.list.d/amneziawg.list
echo "deb-src https://ppa.launchpadcontent.net/amnezia/ppa/ubuntu jammy main" | tee -a /etc/apt/sources.list.d/amneziawg.list
apt-get update

I looked, the necessary headers are installed

# dpkg -l |grep linux-headers|grep `uname -r`
ii  linux-headers-5.15.0-113-generic       5.15.0-113.123                                    amd64        Linux kernel headers for version 5.15.0 on 64 bit x86 SMP

apt-get install -y amneziawg

When installing it shows an error, it cannot build the dkms module

# apt-get install -y amneziawg

Please check

Ensure that you have source repositories configured for APT - run vi /etc/apt/sources.list and make sure that there is at least one line starting with deb-src is present and uncommented.

Yes, yesterday I uncommented deb-src and everything worked
