OK, how about

Code: Select all

apt policy libssl1.1

I'm running Debian stable and wpa_supplicant works just fine for me:

Code: Select all

empty@hegel:~ $ pgrep -a wpa_supplicant
406 /sbin/wpa_supplicant -B -i wlp2s0 -c /etc/wpa_supplicant/wpa_supplicant-wlp2s0.conf

The line with httpredir.debian.org I added from some wiki troubleshooting.
the pgrep -a wpa_supplicant havn't show me anything. But looking at your response I can say that ls /etc/wpa_supplicant response:

• action_wpa.sh
  functions.sh
  ifupdown.sh

No conf file

wpa_supplicant don't know what do, if not configured. wpa_supplicant.conf seems like this.

Code: Select all

network={
ssid="your wifi's SSID"
psk=your wifi's password
}

You might need root privileges already when saving conf, change wpa_supplicant.conf readable only for root:

Code: Select all

chown root:root /etc/wpa_supplicant/wpa_supplicant.conf
chmod 400 /etc/wpa_supplicant/wpa_supplicant.conf

I use ifupdown, this my /etc/network/8nterfaces:

Code: Select all

iface wlan0 inet dhcp
    up /sbin/wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf 
    up dhclient wlan0

Here wlan0 is my wifi interface.

And that's all I need to get wifi working. kernel supports the wifi chip in my notebook.

Yesterday I added 'netowrk' section with my network to /etc/network/interfaces. Today I created wpa_supplicant.conf file and and interfaces file past the same code as yours. On boot up system shows error: 'Failed to start WPA_supplicant '. See systemstl status wpa_supplicant.service. Output of that:

Code: Select all

● wpa_supplicant.service - WPA supplicant

 Main PID: 979 (code=exited, status=127)

ifup wlan0 now seems to have any effect, but still occurs the problem with libraries. Again linked libs (what mr on the stick said is not good), but nothing changes :/

but still no connection (slighty not sure what I am doing...). So much fails and then connection, but I havn't seen any WiFi connection...
What can be wrong with libcrypto? Kernel update could help?

What can be wrong with libcrypto?

The third-party repositories that you have added to your system have polluted your dependency chain and broken wpa_supplicant, your errors cannot be reproduced in a "pure" Debian system.

I can't figure out what's making it want a non-existent library and even if we could there would probably be other broken packages in your system so I think you will have to re-install from scratch and stick to the official repositories next time.

EDIT: the locally compiled version of wpa_supplicant seems to work though so you just need to assign IP addresses to connect.

[arzgi]

I forgot to mention, that I have a pure Debian stetch.

Now you have seen, it can produce severe complications when you use third party packages. There may become even problems, that are more difficult or impossible to solve..

I would give up and do a clean reinstall. So the instructions given would work, and you would not have to fear what might happen next.

I did not see in the thread, or did read selectively, but here it is, read and try to understand:
