Ubuntu 22.04 LTS: Internet is present during installation, but not after

Ridiculous issue during installation Ubuntu 22.04.3 LTS amd64.

At step when I can check “install updates during installation to save time after” WiFi driver present and I can connect to WiFi network. But after driver disappears.

I suppose that driver exists on usb with distro.

I found pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+becomes-0u.deb

cd pool/restricted/b/bcmwl
sudo apt install ./bcmwl-kernel-source_6.30.223.271+becomes-0u.deb

and got a lot of errors like:

Ign:2 http://ru.archive.ubuntu.com/ubuntu jammy-updates/main amd64 libitm1 amd64 12.3.0-1ubuntu1~22.04    
                         
Err:1 http://security.ubuntu.com/ubuntu jammy-updates/main amd64 libcc1-0 amd64 12.3.0-1ubuntu1~22.04                              
  Temporary failure resolving 'ru.archive.ubuntu.com'

UPD
after install: no driver, nothing to enable

    I have read a lot of solutions and all of them recommends to install something without working WiFi adapter, without internet.

    But I found a solution that is suitable for me:

    To use cellular internet via usb cable. Both iOS and Android gave me network to download driver.

    use nmcli

    #determine if the kernel even recognizes the WIFI interface
nmcli d

#Is WIFI on? Should be default
ncmli r wifi on

#Connect

nmcli d wifi connect WIFI-NAME password PASSWORD
