bug#41715: The program '/gnu/store/foobar/compute-guix-derivation' failed to compute the derivation for guix

[o.rojon]

Hello everyone,

on a freshly installed and reconfigured machine, I receive the following 
error:
# guix pull: error: You found a bug: the program 
'/gnu/store/kpxami25fi3mrxb37sfbbx2s366chpk5-compute-guix-derivation'
# failed to compute the derivation for Guix (version: 
"790ada9168e0689c1c4607c61cdc1d2dbc327abf"; system: "x86_64-linux";
# host version: "398ec3c1e265a3f89ed07987f33b264db82e4080"; 
pull-version: 1).

I'm not entirely sure if, in this case, it is about RAM, as has been 
mentioned in this thread: https://issues.guix.gnu.org/41710 . I do have 
24gb ram, but currently a small swap file, but that might be totally 
unrelated.

If I can supply you with more information, please do not hesitate to 
specify how I can aid fixing the issue.

Have a good day,
Olivier

Is there more info above these lines?

I tried to reproduce it with:

  guix time-machine --commit=398ec3c1e265a3f89ed07987f33b264db82e4080 \
    -- time-machine --commit=790ada9168e0689c1c4607c61cdc1d2dbc327abf \
    -- describe

but it works for me.

24 GiB is more than enough.

Is the problem reproducible if you try again now?

Thanks for reporting the issue,

Hi,

I encountered a similar error message today, but it worked fine after
retrying. After digging around in /var/log/guix/drvs, I found these
lines in an appropriately-timestamped log file:

substitute: guix substitute: warning: ci.guix.gnu.org: connection failed: Connection timed out
@ build-started /gnu/store/klyq05c1q8jzwnwrlmvy4ma6m2h6hbk0-compute-guix-derivation.drv - x86_64-linux /var/log/guix/drvs/kl//yq05c1q8jzwnwrlmvy4ma6m2h6hbk0-compute-guix-derivation.drv.bz2 3907994
@ build-succeeded /gnu/store/klyq05c1q8jzwnwrlmvy4ma6m2h6hbk0-compute-guix-derivation.drv -

I do recall seeing the Connection timed out message, I'd even say it's
probably the reason why I decided to retry the pull without much
investigation.

Jakub Kądziołka

[o.rojon]

Hej Ludo,

thanks for the quick reply!

I just tried to pull again and yielded the same result.

Actually, no, there is nothing above these lines. Yet, let me copy/paste 
the whole command in/output. It is in german but I guess the steps are 
so common by now that it shouldnt be a problem to understand :)

# Please report it by email to <bug-guix@gnu.org>.

Also, now I am sure it has nothing to do with ram. Apart from the 
already available ram, I resized my swapdevice.

Is there anything else I should test? One thing I could do is to 
roll-back (I did a upgrade/reconfigure cycle after installation). Should 
I do that and then pull again?

Greetings,
Olivier

bug#41715: The program '/gnu/store/foobar/compute-guix-derivation' failed to compute the derivation for guix

[o.rojon]

Just to follow up: a roll-back does NOT solve the issue.

What I have tried:
1) roll-back via guix system roll-back (to the generation that was 
created upon system installation)
2) roll-back via guix package --roll-back (same)
3) (1) + (2) combined
4) boot into the generation created upon system installation.

In none of these cases was I able to run 'guix pull'.

Does it help for you to see my system configuration file? Because there 
isnt much in there apart from very basic packages (ncdu, recutils, some 
fonts, some icon packs) and a few services (GDM->SDDM login manager, 
MATE desktop, TOR). Also note that before the re-installation, I have 
not experienced problems with this configuration (MINUS mate desktop and 
TOR).

Thanks for testing this.

Note that, if “which guix” returns ~/.config/guix/current/bin/guix, then
none of the rollbacks above can have any effect.  What could make a
difference (but again, that would seem weird to me) is:

  guix pull --roll-back

Are you passing extra options to guix-daemon, such as
‘--cache-failures’?  Or did you enable offloading?

It could also be that a transient failure is causing a silent build
failure somewhere, as Jakub suggests.

Thanks,
Ludo’.

PS: Please keep the bug address Cc’d.

[o.rojon]

Hi Ludo,

guix pull --roll-back did not solve the issue. The only thing I believe 
to have changed is the "host version" portion of the error message.

'which guix' actually points to ~/.configu/guix/current/bin/guix. Should 
this command yield a different value?

I have actually not done anything regarding either guix-daemon or 
offloading. The only things I did after the fresh install were a 
reconfigure and passing a manifest file to 'guix package -m'.

I may have misunderstood what Jakub wrote because I am unsure what a 
transient failure is. The portion I believe to have understood 
essentially says "try again later and it should work".

I found the logs of 'compute-guix-derivation', but I was unable to see 
anything meaningful opening the .drv.bz2 file in emacs. Am I doing 
something wrong?

I wont be on my guix machine for some days now but appreciate pointers. 
:)

OK, that’s expected.

Yes, that’s the essence of it.  :-)

Could you try this:

  strace -s 500 -o log guix pull

and post the ‘log’ file, compressed, somewhere?

Hi Ludo,

here is the log uploaded on mediafire: 
http://www.mediafire.com/file/ldqoi68y88rzrn9/log.bz2/file (note that if 
you can recommend another uploading service, feel free to!)

Since the log is in german, let me specify at least two of the recurrent 
phrases in english:
"Datei oder Verzeichnis nicht gefunden" means "file or directory not 
found"
"Die Ressource ist zur Zeit nicht verfügbar" means "Resource is 
currently unavailable"

If there is other things that need be translated, dont hesitate to tell 
me :)

Greetings,
Olivier

I don’t know, maybe you could run IPFS.

The log reads:

--8<---------------cut here---------------start------------->8---
clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f3d44cfee50) = 1498
close(17)                               = 0
read(16, "", 1)                         = 0
close(16)                               = 0
wait4(1498, [{WIFSIGNALED(s) && WTERMSIG(s) == SIGBUS}], 0, NULL) = 1498
--8<---------------cut here---------------end--------------->8---

… which means the ‘compute-guix-derivation’ process crashed with SIGBUS.

Could you run:

  ulimit -c unlimited
  guix pull

That should fail again, but this time there should be a ‘core’ file in
the current directory (or ‘core.’ followed by digits).

Then you can run:

  gdb --core=./core

and at the GDB prompt, type:

  thread apply all bt

Could you let me know what that returns?

Thanks,
Ludo’.

Hej Ludo,

crazy, I wouldn't have thought it would go as deep as gdb as quickly ;-)

I followed the steps you mentioned, the results you find here: 
https://www.mediafire.com/file/g5yz8f3pput8f3w/gdb-output/file  . The 
only part I omitted from the gdb output is the first lines mentioned the 
license. (Will look at IPFS, maybe next time :))

If you need anything else, dont hesitate to specify. Also, should a 
reinstall become necessary, that would be annoying but not the end of 
the world. So if we hit a dead end thats fine by me.

Thanks a lot for your help. So far, I received only good from the guix 
community :)

Greetings,
Olivier

Since it’s a small file, you can send it as an attachment.

GDB shows:

--8<---------------cut here---------------start------------->8---
Core was generated by `/gnu/store/0m0vd873jp61lcm4xa3ljdgx381qa782-guile-3.0.2/bin/guile --no-auto-com'.

That means debugging info is lacking.  To address that, could you run:

  guix build $(guix gc --derivers /gnu/store/0m0vd873jp61lcm4xa3ljdgx381qa782-guile-3.0.2)

and then:

  echo 'set debug-file-directory /gnu/store/9lg4gssswn2cwn54p6jjy6nld16ah795-guile-3.0.2-debug/lib/debug' >> ~/.gdbinit

At that point, you can try again to run:

  gdb --core=./core

That will hopefully show more useful info.

Thanks in advance!

Hej Ludo,

I see that some time has passed and I believe that the issue can be closed.

Long story short, my hdd has died and I bought a new one and 
re-installed. I could imagine that the errors I was running into were 
related to the impending hardware failure -- that's a speculation, 
though. Anyway, following your suggestions brought me to the same point 
I was at earlier (gdb didnt show anything useful).

Another possible source of error I have not mentioned before (I simply 
forgot about it): after the fresh install, I swapped the swap and /home 
partition using another OS (I have two hdds, each of which has a 
different OS). I don't know if that could've been the problem and/or one 
reason the hdd died.

Anyway, I'm thankful for your supportive attitude and your time.

Have a good day,

Olivier
