I would say that any normal user would just /assume/ that these files were not support and revert to Windows for this task... I found this bug after doing just that in Oneiric. I don't think it's reasonable to close it just becuase you can install a different backend and have it work... it may not be a bug in file-roller (other than that it does not advise the user of options), but perhaps in the distribution planning etc.
Clearly closing this bug without addressing it has lead to the problem being present for 2 full cycles of LTS, and AES zip files are now much more common. Perhaps this can be moved to papercuts? ** Changed in: file-roller (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to file-roller in Ubuntu. https://bugs.launchpad.net/bugs/220654 Title: file-roller will not open 256 AES zip files Status in “file-roller” package in Ubuntu: Confirmed Bug description: Binary package hint: file-roller Winzip and many other zip programs can now produce zip files that are protected by 256 AES encryption. FIle-roller in ubuntu cannot handle these zips. The files within the zips are shown fine but when you try and extract the following error occurs: skipping: Test.txt unsupported compression method 99 I believe this is because "unzip" is used to extract the archive. This is the output from "unzip": dbrewer@HCC122J:~/Desktop$ unzip Test.zip Archive: Test.zip skipping: Test.txt unsupported compression method 99 If "7z" is used it works fine: dbrewer@HCC122J:~/Desktop$ 7z x Test.zip 7-Zip 4.51 beta Copyright (c) 1999-2007 Igor Pavlov 2007-07-25 p7zip Version 4.51 (locale=en_GB.UTF-8,Utf16=on,HugeFiles=on,2 CPUs) Processing archive: Test.zip Extracting Test.txt Enter password (will not be echoed) : Everything is Ok So I propose that file-roller uses "7z" instead of "unzip". I attach an example of this kind of file. The password is "monkey" (no quotes). Note peazip also can handle this. Maybe a replacement for file- roller?
