Subject: "failed to unpack source code" on guix pull
Date: Sat, 13 Aug 2016 18:05:17 -0400

Hey all,

I'm running GuixSD on a Thinkpad X200. I typically run 'guix pull' 
almost every day without any troubles, but about two days ago I started 
getting this error every time I ran the command leaving me unable to 
update my system:

> Starting download of /tmp/guix-file.JNdnA7
> From 
> http://git.savannah.gnu.org/cgit/guix.git/snapshot/master.tar.gz...
>  ….tar.gz                                   1.4MiB/s 00:07 | 10.4MiB 
> transferred
> unpacking 
> '/gnu/store/q4zzpxpbbhwmwh4snisymlpf0p24ddk7-guix-latest.tar.gz'...
> guix pull: error: failed to unpack source code

What's odd about this, is the actual file 
/gnu/store/q4z...-guix-latest.tar.gz, appears to be a valid targz 
archive, and I'm able to unpack and repack that using tar manually just 
fine. 'realpath $(which tar)' returns 
'/gnu/store/ggmmcw327ny831gqd7zvi3hpl5fm23mn-tar-1.28/bin/tar', and I've 
done some basic tests which do confirm that binary seems to work. I'm 
not having any network problems otherwise.

What can I do to further debug / fix this?

P.S. I'm not subscribed to bug-guix, so please CC me in any responses to 
this thread!

Thanks,

I also saw this bug yesterday. Reminds me how luxurious GNU Guix
normally is - for several things to fail at the same time is rare.

This was caused by a patch I sent which was applied on master.
Guix error messages could be more natural, as for me the error output I
got seemed just verbose and I decided it was okay to send this in. The
commit has since then be reverted and I will send in an updated patch.

Simpler explanation: a license I added was already inherited by another
loaded module, this caused some "hick up" and make broke (while it did
not break locally on my side).

>> P.S. I'm not subscribed to bug-guix, so please CC me in any

Can you please close this bug (see the message you got from
debbugs.gnu.org with instructions) when it is done.
For me master builds again, so I assume this bug is done?

I can do that once I get a message (I haven't yet), but for me I'm still 
having the guix pull issue. Are there any steps that need to be done by 
me to ensure I'm getting the latest master branch with the fix? If not, 
when would the fix be applied?

Thanks,

Curious, I thought the normal behavior of debbugs was to send
instructions with how bugs are closed etc. Sometimes there's a very long
delay (I noticed 1-2 days delay with bugs being opened).

Can you describe your problem more in detail and how to reproduce? I've
just run a `guix pull` and the build succeeded for amd64.

I don't think this is the cause of this bug.

If I remember correctly, Harry mentioned this bug on IRC before the
"expat" problem. Also, this problem appears to happen while unpacking
the tarball, and I _think_ that should be possible independent of bugs
in Guix code.

Since nobody has suggested a more precise debugging method, I recommend
you try running the guix-daemon with `strace -f -o logfile` to see
precisely what fails.

[Message part 1 (text/plain, inline)]

Thanks for the help guys, I'm still having this issue. Leo is right that 
I did ask about this on IRC earlier. I've attached the logfile when I do 
"sudo strace -f -o logfile -p 170" and then a "guix pull", where 170 is 
the guix-daemon PID with these arguments: 
"/gnu/store/3g6zn8y5sfwywr4pqiwqrab735a0x4zl-guix-0.10.0/bin/guix-daemon 
--build-users-group guixbuild --substitute-urls 
https://mirror.hydra.gnu.org https://hydra.gnu.org".

I'm pretty sure PID 1516 is the actual "guix pull" command. What seems 
to be the problem based on this log? What can be done to fix it?

`guix pull` has been completely overhauled since the bug was filed so
I'm closing it.
