Hello everyone,

I'm recently running into problems updating my system. I had not 
reconfigured for a while (1~2 months) and now, when I reconfigure, I get 
the error message below.
At first I thought it might be related to a specific guix commit, but I 
have now tried four times over the course of 2 weeks, and I always get 
the same error.

Strangely enough, the only reason why I noticed something is not right 
is that nouveau's displaying behaviour would be weird after updating.
That is, it seems to either have changed my desktop resolution or 
applied a form of magnification on all text displayed (sddm, terminal, 
...)
I have no actual clue if these two things are related to each other AT 
ALL. I was just confused, because if they were totally unrelated,
I would struggle to understand why these two things happen concurrently 
;-)


While the error message is in german, I believe to have translated the 
more important chunks in the Subject field.

##### error message #####
guix system: Bootloader erfolgreich auf „/dev/sdb“ installiert
guix system: error: Ausnahme aufgetreten bei der Ausführung von „start“ 
auf Dienst „file-system-/sys/kernel/debug“:
Throw to key `match-error' with args `("match" "no matching pattern" 
("none" "/sys/kernel/debug" "debugfs" () #f #f #f))'.
#######################

As always, any help is appreciated. One good thing is that I finally 
learn the virtues of roll-back and switch-generation :)

Have a good day,
Olivier

I have this same issue on my Thinkpad, no Nouveau. I also had issues on
my AMDGPU setup. If it's related to graphics, it doesn't seem driver
specific.

It seems that reconfigure only fails during the build phase, not when
it's actually activating the new system, because running reconfigure
again causes no errors.

Yes this is harmless error that goes away by reconfiguring again. This
has been discussed here: https://issues.guix.gnu.org/42826.

Thanks,
