zip file for download of multiple files appears corrupted

benedetto commented 9 years ago

Steps to reproduce

Select multiple files in the web interface and hit "download" to get a zip file containing all the files
Download it to your computer
Try to open it on a Linux system
Expected behaviour

The file should open/extract into the selected files

Actual behaviour

If I try to open it with a Linux GUI program for archive handling (Ark in my case) I only get an error message telling me that the file cannot be opened because it is corrupted. If I instead try to extract it with the extraction function in the context menu of my file manager, the whole archive is extracted into a file that has the name and the content of the first file of the zip archive but the size of the whole archive.

If I use unzip download.zip on the command line instead, the archive is extracted correctly. This happens to me on both owncloud instances I administer and I had several Linux users complaining about the issue.

What version of ark are you using? Can you provide any information which libraries it uses? (maybe there is something in the help window?)

benedetto commented 9 years ago

In my case it's Ark 2.19 on KDE 4.14.2. According to apt it depends on

libarchive12
libc6 (>= 2.14)
libkdecore5
libkdeui5
libkfile4,
libkhtml5
libkio5
libkonq5abi1
libkparts4
libkpty4,
libqt4-dbus (>= 4:4.5.3)
libqtcore4 (>= 4:4.7.0~beta1)
libqtgui4 (>= 4:4.5.3)
libstdc++6 (>= 4.1.1)

and recommends

bzip2
p7zip-full
unzip
zip

I would guess that the archive handling is basically provided by libarchive12 and the recommended command line tools for the different zip formats.

Upstream: https://bugs.kde.org/show_bug.cgi?id=353266 + https://github.com/McNetic/PHPZipStreamer/issues/25

tl;dr: Not much we can do. Use another application to open the ZIP file.
