How to investigate a recurring problem with system updates or add-on updates?

Installation Home Assistant OS

Hi

Let me explain a little my issue and the history. I have HAOS running on a dedicated NUC since few years now without any problems till recently !
Six months ago, I got an hardware issue and so changed the SSD inside and restored HA from nabu casa backup (out of the db that HAOS was unable to restore so restarted from zero for db).
Since 3 months now I have a recurring problem to do updates whatever it is HAOS, HA, supervisor or add-ons like ESPHome for example.
Most of time I can’t even start the update from Lovelace, button of update is doing nothing or it starts and then hang for ever.
I have checked multiple times the logs of supervisor and system but nothing at all in it :frowning:
I’m quite lost what to investigate considering that nothing shows up in logs :frowning:
Something else that might be related or not: in the past I could do a host reboot from HA without problems now it’s no more possible, it shuts down the machine and hangs there !
I don’t have any problems of space on storage and storage itself is good (verified SMART datas).
Usually if I do a hard reboot which implies power cut, I’m able to do 1/2 upgrades and then again it’s stuck. Right now I have the latest update of ESPHome pending but when I click on the update button nothing at all happens (not even a popup of supervisor to indicate a problem or something in logs !).

Thanks for help,

Vincèn

There’s a mantra I here oin this forum often, sometimes from me.

IT’S ALWAYS DNS…

Is there a chance that you are running PiHole or AdGuard?
Are you relying on an ISP owned device as your WIFI and Firewall?
Are you running VLANs?
Is your DNS correct in HA?

You are right, DNS can be the source of a lot of tricky problems :wink: but here nothing special for DNS: no PiHole or Adguard, I own my router that is a “clean” device (DEC 740 OPNSense) with proper DNS both for IPv4 and 6 :wink:
No VLAN and DNS in HA are the one of my router and HA has a fixed LAN IP address.

I found that error message in HAOS system log generated by NetworkManager all the time (although everything is working fine with network for HA):

request-scan: could not get scan request result: The connection is closed

Can’t find anything about it in forum or on internet so not sure what the problem is as HA has internet access working fine !
