I think I solved the problem now. I also placed a question on ubuntuforums.org, and I got a tip here. What I did was replace the lines
Listen localhost:631 Listen 10.0.0.145:631 with the line Listen 0.0.0.0:631 in the cupsd.conf file. Now I can access the CUPS web interface on my server from a client machine in the network. -- cups: 127.0.0.1:631 - Address already in use. https://bugs.launchpad.net/bugs/304393 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
