Отлично, теперь попробуйте
sudo apt update

наконец-то заработало))
спасибо большущее
и раз уж вы тут пока, может объясните мне пошагово, как установить последний bluez?
этот у меня через неделю почему-то отваливается и больше не включается(

спасибо большущее

Вот и славно
Можете вернуть свой DNS-сервер:
sudo sh -c 'echo "nameserver 192.168.1.1" > /etc/resolv.conf'

Вот прям самый-самый последний?
sudo apt build-dep bluez
sudo apt install libebook1.2-dev
git clone https://salsa.debian.org/bluetooth-team/bluez
cd bluez
dpkg-buildpackage -uc -b -d
cd ..
sudo apt install ./bluetooth_5.77-1_all.deb ./bluez_5.77-1_amd64.deb ./libbluetooth3_5.77-1_amd64.deb ./libbluetooth-dev_5.77-1_amd64.deb
Но это на ваш страх и риск
Так можно и весь apt сломать

большое вам спасибо!

к сожалению блютуз так и не заработал (встроенный в мини пк), хотя при установке и еще неделю работает
стоит-ли удалять новый блютуз или оставить все как есть?
а вот если свисток воткнуть, работает, но он и на старом работал...

Ну если хотите, можете удалить

благодарю, все ок
а из-за чего может встроенный блютуз отваливаться, нет предположений? при этом если proxmox стоит в нем не отваливается
