I got ar_YE.ISO-8859-6...LC_MONETARY: value of field `int_curr_symbol' does not correspond to a valid name in ISO 4217 es_GT.ISO-8859-1...LC_MONETARY: value of field `int_curr_symbol' does not correspond to a valid name in ISO 4217 sv_FI.ISO-8859-15@euro...LC_MONETARY: value of field `int_curr_symbol' does not correspond to a valid name in ISO 4217 ar_SY.UTF-8...LC_MONETARY: value of field `int_curr_symbol' does not correspond to a valid name in ISO 4217 es_ES.UTF-8...LC_MONETARY: value of field `int_curr_symbol' does not correspond to a valid name in ISO 4217 sv_FI.UTF-8...LC_MONETARY: value of field `int_curr_symbol' does not correspond to a valid name in ISO 4217 sv_FI.UTF-8@euro...LC_MONETARY: value of field `int_curr_symbol' does not correspond to a valid name in ISO 4217 while rebuilding glibc-2.2.90-14.
