Package: printer-driver-cups-pdf Version: 3.0.1-5 Severity: normal
The PDF driver is failing to write the output PDFs. For example, a command like
echo foo | lp -d PDF
yields the following DEBUG output in the log:

Wed Jul 3 09:40:55 2019 [DEBUG] all memory has been freed
Not only is the output file unlinked right after the call to
/usr/bin/gs; This call itself also fails with a "permission denied"
error, according to strace:
[pid 2545] openat(AT_FDCWD, "/home/ssd/madduck/PDF/stdin___madduck_PDF.pdf", O_RDWR|O_CREAT|O_TRUNC, 0666) = -1 EACCES (Permission denied)The target directory is 0700, but even changing it to 1777 doesn't fix things.
Note that if I reduce the LogLevel to 3 in /etc/cups/cups-pdf.conf, then the log output suggests that PDF creation is being successful, after failing to set the file mode:
Wed Jul 3 09:44:00 2019 [ERROR] failed to set file mode for PDF file: /home/ssd/madduck/PDF/2019-07-03-094400-740472161-muttprint.pdf (non fatal) Wed Jul 3 09:44:00 2019 [STATUS] PDF creation successfully finished for madduckAgain, using strace, the error derives from the following call to chmod
[pid 2543] chmod("/home/ssd/madduck/PDF/stdin___madduck_PDF.pdf", 0600) = -1
ENOENT (No such file or directory)
which obviously fails, as the file has never been created, and it
was unlinked anyway.
Finally, please note that I have a second sid system, pretty much identical to this one, with an identical cups-pdf.conf file, but there, the PDF file is written just fine.
Also note that this used to work, but recently stopped working on this machine. Unfortunately, I am unable to say what has changed since then, as I didn't take note when the problem first appeared.
