two issues on OPNsense 26.1.3-amd64

[andreasglashauser]

I currently have two different issues, I am not sure whether they are related or not.

The first issue existed for some time already: I can't update my system anymore without manual intervention.
I usually update my system via cron and it doesnt work because my system never reboots. If i click  "Click to check for updates." via the dashboard I can see that all updates where downlaoded, but that there are problems with rebooting. I get the popup dialog that shows "Performing reboot to finish this update. The system is being rebooted at the moment, please wait...". However, it never reboots and after some time i get redirected to the dashboard again.

I noticed it already on 25. What I initially did was that I access my system via ssh, ran various commands I unfortunately dont remember (I think i deleted the update cache, deleted some /var/log files, and other stuff. I dont know what really solved the issue unfortunately, I always thought this was the last time I would have to do this...)

The (new?) crash reporter shows the following:

Unfortunately I have disabled ssh a while back, and here we come to my other issue: I can't enable ssh anymore. If I enable "Enable Secure Shell" and "Permit root user login" via the dashboard, I get the following fatal error:

Fatal error: Uncaught TypeError: fwrite(): Argument #1 ($stream) must be of type resource, false given in /usr/local/etc/inc/system.inc:1328 Stack trace: #0 /usr/local/etc/inc/system.inc(1328): fwrite(false, '#\n') #1 /usr/local/www/system_advanced_admin.php(390): system_login_configure() #2 {main} thrown in /usr/local/etc/inc/system.inc on line 1328

If I go back to the dashboard and to the settings page again, I can see that both options are checked so it was saved, but ssh doesnt work.

Disk full perhaps?


Cheers,

[andreasglashauser]

Nope, disk has more than enough space. also zfs doesnt show any errors.

I just manually rebooted it and it is the first time that this fixed my issue... even ssh access works now...

I will still let this thread open. I am very sure that something similar happens upon the next update, because I got these consistently in the past.

Sorry, I seem to not get it, as this isnt my area of expertise. Whats wrong with it?

[Monviech (Cedrik)]

Oh sorry I forgot the context. There has been a microcode update that caused some reboot issues or something. I read about it on reddit.

If you don't 100% need the microcode updates you most likely are better off stability wise without the plugin. (personal opinion, no expert on that matter)

I will try it out next time and consider it. Thanks.
