I found that in my case the problem is that the package "p7zip" does not support password encryption on file creation.
I then installed the package "p7zip-full" and then it started to work, even with the file-roller integration which was nice. I wonder what is the point of having two packages (p7zip and p7zip-full) in the first place, this is all quite confusing. But at least it worked -- 7zip fails to encrypt, says "E_FAIL" https://bugs.launchpad.net/bugs/246861 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
