Package: smbclient Version: 2:4.9.11+dfsg-1 Followup-For: Bug #931717
Here's the thing: if you replace /usr/lib/cups/backend/smb with a shell script that simply calls smbspool: #!/bin/sh exec /usr/bin/smbspool "$@" it works. I wanted to debug if DEVICE_URI was set correctly, and it is. The documentation of smbspool mentions that it tries to use ARGV[0] if it starts with a smb:// prefix. I assume cups sets ARGV[0] to the internal device_uri, which strips the username/password (as seen in the web interface) and smbspool will now take this value instead of DEVICE_URI. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (900, 'unstable'), (800, 'experimental'), (500, 'unstable-debug') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-5-rt-amd64 (SMP w/8 CPU cores; PREEMPT) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages smbclient depends on: ii dpkg 1.19.7 ii libarchive13 3.3.3-4 ii libbsd0 0.9.1-2 ii libc6 2.28-10 ii libpopt0 1.16-12 ii libreadline8 8.0-2 ii libsmbclient 2:4.9.11+dfsg-1 ii libtalloc2 2.1.14-2 ii libtevent0 0.9.37-1 ii samba-common 2:4.9.11+dfsg-1 ii samba-libs 2:4.9.11+dfsg-1 smbclient recommends no packages.
