Hi Guix, A lesson learnt from a previous update process [1] was; do not leave it too long between 'guix pull' updates.
However, I have one system running Ubuntu 16.04 and Guix v0.12 that I am trying to update. As root: $guix package --list-installed glibc-utf8-locales 2.25 out /gnu/store/g4g0zhcp5j9 pyjmcv02ks4x2b48k252x-glibc-utf8-locales-2.25 guix 0.12.0-9.25a4 out /gnu/store/nqy9m6hhnkkfwr5w yq5bac96v9s9hc9i-guix-0.12.0-9.25a4 gnutls 3.5.9 out /gnu/store/56dbd2gw33g3wdxmq78lr3 9lamg8gxnq-gnutls-3.5.9 nss-certs 3.30.2 out /gnu/store/3ql0vilc0zv6ra42gh i04787vrg6bb71-nss-certs-3.30.2 When I do 'guix pull' I get an error. The backtrace suggests reporting a bug: Backtrace: In unknown file: ?: 19 [primitive-load-path "guix/store" ...] In ./guix/store.scm: 20: 18 [#<procedure 167b020 ()>] In ice-9/boot-9.scm: 2987: 17 [define-module* (guix store) #:filename ...] 2962: 16 [resolve-imports (((guix utils)) ((guix config)) ((guix memoization)) ...)] 2900: 15 [resolve-interface (guix utils) #:select ...] 2825: 14 [#<procedure 16ffb40 at ice-9/boot-9.scm:2813:4 (name #:optional autoload version #:key ensure)> # ...] 3101: 13 [try-module-autoload (guix utils) #f] 2412: 12 [save-module-excursion #<procedure 18d53c0 at ice-9/boot- 9.scm:3102:17 ()>] 3121: 11 [#<procedure 18d53c0 at ice-9/boot-9.scm:3102:17 ()>] In unknown file: ?: 10 [primitive-load-path "guix/utils" ...] In ./guix/utils.scm: 26: 9 [#<procedure 17760a0 ()>] In ice-9/boot-9.scm: 2987: 8 [define-module* (guix utils) #:filename ...] 2962: 7 [resolve-imports (((guix config)) ((srfi srfi-1)) ((srfi srfi- 9)) ...)] 2900: 6 [resolve-interface (guix config) #:select ...] 2825: 5 [#<procedure 16ffb40 at ice-9/boot-9.scm:2813:4 (name #:optional autoload version #:key ensure)> # ...] 3101: 4 [try-module-autoload (guix config) #f] 2412: 3 [save-module-excursion #<procedure 18f3090 at ice-9/boot- 9.scm:3102:17 ()>] 3121: 2 [#<procedure 18f3090 at ice-9/boot-9.scm:3102:17 ()>] In unknown file: ?: 1 [primitive-load-path "guix/config" ...] In ./guix/config.scm: 1: 0 [#<procedure 1790d40 ()>] ./guix/config.scm:1:437: In procedure #<procedure 1790d40 ()>: ./guix/config.scm:1:437: In procedure module-lookup: Unbound variable: and=> guix pull: error: You found a bug: the program '/gnu/store/d9dc5jdlhbp4zdx1m9ffr3fmhyg60zy8-compute-guix-derivation' failed to compute the derivation for Guix (version: "20181217.11"; system: "x86_64-linux"; host version: "20170504.14"; pull-version: 0). Please report it by email to <bug-g...@gnu.org>. However, I remember that the package guile-git was not a dependency at the time of v0.12 but it is now. So, rather than reporting the bug I have tried to install guile-git: $ guix package -i guile-git Starting download of /gnu/store/c3npgqn9ag2ypi9bda1g779wwwlcqqrf- libgit2-0.25.1.tar.gz >From https://github.com/libgit2/libgit2/archive/v0.25.1.tar.gz... following redirection to `https://codeload.github.com/libgit2/libgit2/t ar.gz/v0.25.1'... v0.25.1 1.3MiB/s 00:03 | 4.1MiB transferred output path `/gnu/store/c3npgqn9ag2ypi9bda1g779wwwlcqqrf-libgit2- 0.25.1.tar.gz' should have sha256 hash `1cdwcw38frc1wf28x5ppddazv9hywc718j92f3xa3ybzzycyds3s', instead has `0ywcxw1mwd56c8qc14hbx31bf198gxck3nja3laxyglv7l57qp26' This has been reported before [2]. The workaround suggested there was to download the source directly. However, this now fails too: $ guix download https://mirror.hydra.gnu.org/file/libgit2-0.25.1.tar.g z/sha256/1cdwcw38frc1wf28x5ppddazv9hywc718j92f3xa3ybzzycyds3s ERROR: Throw to key `gnutls-error' with args `(#<gnutls-error-enum Error while reading file.> set-certificate-credentials-x509-trust- file!)' I think the error message is a little misleading here. I have tried to download the same file from a more recent guix installation on another system which also fails. Essentially, the error is 'file not found'. So, the situation is that neither a substitute nor the source code are available for libgit2 and Guix gets stuck. How should one resolve cases such as this? Best regards, Paul.
