Hi,

Indeed, the package ’ugrep’ is not reproducible:

 guix build ugrep --no-grafts -q
 guix build ugrep --no-grafts -q --check -K
 diff --no-dereference -r /gnu/store/a6x7rv7xi3d2pw205znmnha9qfjrvs7k-ugrep-3.1.12{,-check}
 Binary files /gnu/store/a6x7rv7xi3d2pw205znmnha9qfjrvs7k-ugrep-3.1.12/bin/ugrep and /gnu/store/a6x7rv7xi3d2pw205znmnha9qfjrvs7k-ugrep-3.1.12-check/bin/ugrep differ

The next step is to investigate with diffoscope.


Well, another data point – maybe Berlin has an issue – because I get:

  guix challenge ugrep --substitute-urls="https://ci.guix.gnu.org https://bordeaux.guix.gnu.org"
  /gnu/store/a6x7rv7xi3d2pw205znmnha9qfjrvs7k-ugrep-3.1.12 contents differ:
    local hash: 1ifdjmscb07pacxwcs2408zi12yrxxf0zdwzz800xlccp5x53m7r
    https://ci.guix.gnu.org/nar/lzip/a6x7rv7xi3d2pw205znmnha9qfjrvs7k-ugrep-3.1.12: 1ifdjmscb07pacxwcs2408zi12yrxxf0zdwzz800xlccp5x53m7r
    https://bordeaux.guix.gnu.org/nar/lzip/a6x7rv7xi3d2pw205znmnha9qfjrvs7k-ugrep-3.1.12: 1yf9752hprihmhwnqlhaffkmwmkd3scwzr8dqy7d78vcy70qjkn6

  guix hash -r $(guix build --no-grafts ugrep)-check
  1yf9752hprihmhwnqlhaffkmwmkd3scwzr8dqy7d78vcy70qjkn6

I fetch by default the substitutes from ci that why “local hash“ and ci
are the same; but my local build with ‘guix build --check’ gives the
same hash as bordeaux.


All the best,
simon
