Package: skanlite
Version: 22.12.3-1

Skanlite fails to scan, the scanner is an HP ENVY 6030e, I started
Skanlite from command-line when I click "Scan" button these lines appear
in Konsole:

~$ skanlite -d escl:https://192.168.0.89:443
<?xml version="1.0" encoding="UTF-8"?>
<ErrorInfo

a popup window then is shown with this localized message:

"Alimentatore dei documenti vuoto"

(translated to English with Google Translator: "Document feeder empty")

the locale's output:

~$ locale
LANG=it_IT.UTF-8
LANGUAGE=
LC_CTYPE="it_IT.UTF-8"
LC_NUMERIC="it_IT.UTF-8"
LC_TIME="it_IT.UTF-8"
LC_COLLATE="it_IT.UTF-8"
LC_MONETARY="it_IT.UTF-8"
LC_MESSAGES="it_IT.UTF-8"
LC_PAPER="it_IT.UTF-8"
LC_NAME="it_IT.UTF-8"
LC_ADDRESS="it_IT.UTF-8"
LC_TELEPHONE="it_IT.UTF-8"
LC_MEASUREMENT="it_IT.UTF-8"
LC_IDENTIFICATION="it_IT.UTF-8"
LC_ALL=

the workaround I found is to set LC_ALL=C environment variable at the
beginning of the command:

~$ LC_ALL=C skanlite -d escl:https://192.168.0.89:443

doing so Skanlite makes scan regularly.

Cheers
