Hi! So the guts of the problem is that Guile’s ‘string->uri’ procedure behaves incorrectly under that locale:
--8<---------------cut here---------------start------------->8--- $ export GUIX_LOCPATH=$(guix build glibc-locales)/lib/locale $ LANGUAGE= LC_ALL=sv_SE.utf8 ./pre-inst-env guile GNU Guile 2.2.4 Copyright (C) 1995-2017 Free Software Foundation, Inc.

Enter `,help' for help. scheme@(guile-user)> ,use(web uri) scheme@(guile-user)> (string->uri "ftp://sourceware.org/pub/libffi/libffi-3.2.1.tar.gz";) $1 = #f --8<---------------cut here---------------end--------------->8--- More specifically, ‘parse-authority’ is failing under that locale, because of the “w”: --8<---------------cut here---------------start------------->8--- scheme@(guile-user)> ((@@ (web uri) parse-authority) "//sourceware.org" (const 'fail)) $5 = fail scheme@(guile-user)> ((@@ (web uri) parse-authority) "//sourcevare.org" (const 'fail)) $6 = #f $7 = "sourcevare.org" $8 = #f --8<---------------cut here---------------end--------------->8--- We can boil it down to this example: --8<---------------cut here---------------start------------->8--- scheme@(guile-user)> ,use(ice-9 regex) scheme@(guile-user)> (string-match "[a-z]" "a") $10 = #("a" (0 . 1)) scheme@(guile-user)> (string-match "[a-z]" "w") $11 = #f --8<---------------cut here---------------end--------------->8--- In short, under the sv_SE.utf8 locale of glibc 2.28, “w” is not considered part of the ‘a-z’ interval. Indeed, ‘localedata/locales/sv_SE’ in glibc reads this: % The letter w is normally not present in the Swedish alphabet. It % exists in some names in Swedish and foreign words, but is accounted % for as a variant of 'v'. Words and names with 'w' are in Swedish % ordered alphabetically among the words and names with 'v'. If two % words or names are only to be distinguished by 'v' or % 'w', 'v' is % placed before 'w'. Using the “lower” regexp class instead of “[a-z]” works: --8<---------------cut here---------------start------------->8--- scheme@(guile-user)> (string-match "[[:lower:]]" "w") $12 = #("w" (0 . 1)) --8<---------------cut here---------------end--------------->8--- However, it’s not clear to me whether the “lower” class is supposed to be the same for all locales or if we’re just lucky: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html Thoughts? The workaround until we’ve fixed it is to use another locale, though you can still set “LC_MESSAGES=sv_SE.utf8” or “LANGUAGE=sv”. Ludo’.
