Hi bo0od, Your subject was quite dramatic and probably not true. Try to avoid both. bo0od writes: > The real issue it caused guix to freeze for like not less than > 2+ > hours and i couldnt do anything with the distro until guix cut > out > the build/upgradation by itself. Take a look at (and next time, attach) $ bzless /var/log/guix/drvs/5a/8xxi15g20iqr78daw3w1c7xyqmmd1k-vigra-1.11.1.drv.bz2 the log file mentioned in the error message. You'll probably find the string ‘Killed’ near the end. If you haven't rebooted yet, $ grep oom /proc/vmstat will probably return something non-zero. If so: you ran out of memory while building a heavy package. This causes your system to become unresponsive whilst it tries to postpone that for as long as possible. This is a fact of Linux. You can try to work around it by adding RAM, passing ‘-{M,c}1’ to the guix command that failed, and/or enabling swap, but the root cause is you simply don't have enough memory to build this package at its default settings. Or, you can make sure you download a substitute instead of trying to build everything locally. At the time of writing (commit d14f213) there's a libreoffice substitute on ci.guix.gnu.org. Are substitutes configured and enabled? Kind regards, T G-R
