The error message normally says something like:

View build log at /var/log/guix/drvs/…

Could you post that file?

Also, what is the output of “uname -sr” on this machine?

Thanks in advance!

The log you posted reads this:

Toggle snippet (13 lines)
Creating 4.0 filesystem on /gnu/store/mhhlqyazyvwz72y6dwh56fs1zlrvrl0h-squashfs-pack.gz.squashfs, block size 131072.

[...]

Number of uids 2
unknown (0)
nixbld (987)
Number of gids 2
unknown (0)
nixbld (980)
Failed to read existing filesystem - will not overwrite - ABORTING!

I was able to reproduce it on a CentOS 7 system and to strace the
‘mksquashfs’ process, and found that this had to do with access to
SELinux extended attributes.

Fixed in commit 53c594cb3f1f783fea18be6da23a863b00c14f5f.

Thanks!

Thanks! I look forward to my increased use of `guix` ?
