System freeze-up

[j8a]

Hi [member=9729]lintek[/member] ,
I think you have the Network Manager down which can be solved whether you could type the folloswing command in a terminal:
systemctl status avahi-daemon.service

The output text on the terminal looks like this:

systemctl status avahi-daemon.service
● avahi-daemon.service - Avahi mDNS/DNS-SD Stack
    Loaded: loaded (/lib/systemd/system/avahi-daemon.service; enabled; vendor >
    Active: active (running) since Wed 2021-05-12 15:43:13 -03; 12min ago
TriggeredBy: ● avahi-daemon.socket
  Main PID: 655 (avahi-daemon)
    Status: "avahi-daemon 0.7 starting up."
      Tasks: 2 (limit: 9042)
    Memory: 2.1M
    CGroup: /system.slice/avahi-daemon.service
            ├─655 avahi-daemon: running [jochoa-pc.local]
            └─730 avahi-daemon: chroot helper
.......

Then, go to your Network Manager icon on the task bar and click on it and disable Enable Networking (whichi is ticked).
Afterwards, click on the icon and check the Enable Networking.


Hope this help, regards
