I'm having the same problem with the in-repo version. root@Chuck:/home/claudio# apt-cache policy pdfsam pdfsam: Installed: 1.1.4-2 Candidate: 1.1.4-2 Version table: 1.1.4-2 0 1001 http://ftp.debian.org/debian/ sid/main amd64 Packages
I'm currently downloading the source files for 2.2.2, so I can confirm that that version is working. Cheers, Claudio
