This issue aims to document error messages in Guix that need to be improved. If you get an error message and you have no idea what it's trying to tell you, please send it here!
~ Unbound variable while building package cache This might be a Guile or Guix thing, not sure which. Using the recent libpng/guix-gaming problem as an example: --- Generating package cache for '/gnu/store/1mzdd7rf9r34xiibcs1gpjsf7jkh6a0r-profile'... (exception unbound-variable (value #f) (value "Unbound variable: ~S") (value (libpng-1.2)) (value #f)) --- This error message doesn't tell you *where* the unbound variable is, which means people may (and have! <https://issues.guix.gnu.org/56012>) report this as a Guix issue, not a guix-gaming issue. This error should perhaps look something like --- Error: Unbound variable `libpng-1.2' in gaming/packages/whatever.scm --- ~ Network disconnection while downloading things When the network disconnects during a download, Guix usually either hangs or says something like "corrupt archive while restoring input from socket" (I haven't been able to reproduce this, so I don't remember the exact message). Guix should probably poll the network and check whether it's down, then report an error and try to reconnect for perhaps 30 seconds before giving up.
