I am using guix on Ubuntu 19.04, due to some unrelated BTRFS problems I needed to free some space and did a quick:
$ rm -rv /gnu/store/*libreoff* This expectedly confuses guix a little and leads to error messages such as this which make it impossible to reinstall any packages: $ guix install libreoffice guix install: warning: Consider running 'guix pull' followed by 'guix package -u' to get up-to-date packages and security updates. guix install: error: opening file `/gnu/store/kmyp9i01aci0azxwcll41kmn347616q7-libreoffice-orcus.patch.drv': No such file or directory However trying to clean up the issue with "guix gc --verify" unexpectedly fails as well, this time with a failed SQLite constraint, this seems like a bug: $ guix gc --verify reading the store... checking path existence... path `/gnu/store/96ry03xc73c67xs7aj2pnird7icnk578-libreoffice-6.1.5.2.drv' disappeared, but it still has valid referrers! path `/gnu/store/a1hnx6vgwlnqf4fshfln9ljnp9d8y9pl-libreoffice-6.1.5.2.drv' disappeared, removing from database... guix gc: error: executing SQLite statement: FOREIGN KEY constraint failed $ guix --version guix (GNU Guix) 84d7784afe00dfc23c7feeb7ede6bce73406760b
