eth0 disappeared after jessie->stretch upgrade

[Hiisi]

Hi!
To get some fresh software I have committed an upgrade of jessie to stretch. Did it by editing the file /etc/apt/sources.list, then

Code: Select all

sudo apt-get update

followed by

Code: Select all

sudo apt-get upgrade

and

Code: Select all

sudo apt dist-upgrade

Everything went fine and I'm nearly happy with the result. Except for one thing - I've lost connectivity
ifconfig now reports that there's no eth0 interface. Instead there's some 'enxb827ebc1711c'. Where it came from I have no idea. in /etc/network/interfaces I still have my old configuration with correct settings for eth0 and not a word about this new one. Tried to use dpkg-reconfigure to correct network-manager issues and discovered that network-manager is not installed. Also checked with

Code: Select all

dpkg -l | grep network-manager

Any ideas how to fix this?

"enxb827ebc1711c" is a good interface name, it's just something new, you asked for it: https://www.freedesktop.org/wiki/Softwa ... faceNames/

To reverse this, write a fresh new Jessie image to the SD card.

And, in my personal opinion, it's a bad idea to upgrade the whole OS just for getting some new.

Thanks for reply! Did fresh install. Everything is back to normal.
