unsupported compression method 99
Last modified: 2013-03-13 01:44:03 EDT
Description of problem: unzip fails to uncompress a zip file. #unzip foo.zip Archive: foo.zip skipping: bar.wmv unsupported compression method 99 # file foo.zip foo.zip: Zip archive data, at least v2.0 to extract My understanding is that, it is a password protected zip file created in Windows using PKZIP Version-Release number of selected component (if applicable): unzip-5.52-9.fc9.i386 Additional info: 7zip works perfectly on the same zip file
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Package maintainer was changed -> changing the bug owner.
Compression method 99 indicates the AES encryption. Maybe it will be supported in the next upstream release: http://www.info-zip.org/board/board.pl?m-1253652145/ It is not trivial to implement it, therefore I am closing it as WONTFIX.
Unzip tool 7z can handle AES decompression: 7z x foo.zip In Debian you can install p7zip-full to get this tool, probably they have similar thing for RH.
Hi, since I'm having the same issue with RHEL 6.3 I'm responding to this old thread. Here is how to fix it: Enable the EPEL and RPM-Fusion repositories (google how to do it) type in: sudo yum --enablerepo=rpmfusion-free-updates --enablerepo=rpmfusion-nonfree-updates --enablerepo=epel install p7zip Now just doubleclick your encrypted zip-file... ---------------------------------------------------------------------------------- Romeo Kienzler https://www.ibm.com/developerworks/mydeveloperworks/profiles/user/RomeoKienzler ----------------------------------------------------------------------------------
