Hi, I encountered the same so I did some testing. I installed gnome's file-roller and it unzips password protected 7z files without problem. 7z and p7zip both work flawless from the commandline.
So the problem is indeed limited to engrampa (version 1.26.2-4 according to apt policy) I hope this extra info is of any use to help fix the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2054885 Title: Engrampa cannot open password-protected 7zip file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/engrampa/+bug/2054885/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
