3.0.1 - Release Build
Make it short: I wanted to update my System but there are no packages loaded, although 28 are availible. After some hours, the issue is, that I cannot get any data from the internet.
- SSH via w-lan: ok
- Ping within my w-lan: ok
2.1. Desktop PC can ping the Raspberry and Raspberry can ping Desktop
Ping www.heise.de: not
- openhabian@openhabian:~ $ ping www.heise.de
- PING www.heise.de (193.99.144.85) 56(84) bytes of data.
- ^C
- — www.heise.de ping statistics —
- 2 packets transmitted, 0 received, 100% packet loss, time 19ms
Since I ping www.heise.de the DNS translates it correctly into its IP
All other devices in the same w-lan can access the internet.
I am just using Linux and have some rough idea of the theory. But how all the settings in Linux are made? I have no clue. Just searching the internet:
ip a
was always requested. This is the output:
openhabian@openhabian:~ $ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

And
openhabian@openhabian:~ $ sudo nano /etc/network/interfaces`
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

I would by happy, if someone could help me.
