No access to files from Internet Explorer

[lizculver]

When I click on a file in Ubuntuone in IE7 it opens a new IE7 page with the error message:
'Internet Explorer cannot display the webpage

   Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.

   What you can try:
     Diagnose Connection Problems

     More information

This problem can be caused by a variety of issues, including:

Internet connectivity has been lost.
The website is temporarily unavailable.
The Domain Name Server (DNS) is not reachable.
The Domain Name Server (DNS) does not have a listing for the website's domain.
If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section.

For offline users

You can still view subscribed feeds and some recently viewed webpages.
To view subscribed feeds

Click the Favorites Center button , click Feeds, and then click the feed you want to view.

To view recently visited webpages (might not work on all pages)

Click Tools , and then click Work Offline.
Click the Favorites Center button , click History, and then click the page you want to view.'

I have tried to open a file at work and home with the same result. When I use firefox I can download/access my files.

I'm sorry to hear the Ubuntu One web UI isn't working properly for you. We've tested the web UI in Internet Explorer and have not seen this particular issue before. I'm assuming you're able to reach other web sites in IE 7 OK? If so, can you try going to https://one.ubuntu.com and let me know if you get the same results? Thanks!

The same problem occurs if you try to download a publicly available file via its short url using Internet Explorer.

This is caused by the deflate compression of the server. In RFC 2616 it is stated that Content-Encoding: deflate means that the data is compressed by zlib which is a small (usually 2 byte) wrapper around deflate compression. However IE expects directly deflate compressed data, no zlib wrapper. Thus it fails parsing the ubuntu one server's respone. (source: http://www.subbu.org/blog/2008/03/ie7-deflate-or-not)

It is not a bug in Ubuntu One but in Microsoft Internet Explorer. However it would be nice if deflate compression could be disabled for IE or the compression could be changed to make downloading files work in IE.

I have experienced the same bug - I need Internet explorer to work because this is the only internet browser available at my university, so without access to my files, ubuntu one is pretty much a deadweight for me.

It surprises me that only 2 people have commented on this so far?

This is happening for me also, and it makes the service completely unusable for me. I'm using IE8 however from a college account - nothing else is available.

I also get this error .. it is incredible that you have to enliven such a huge mistake on a product that will cost me $ 120 a year ...
Although Ubuntu is one of the beta would be expected to Canonical tests in each case, IE7 IE8 and Firefox, Safire ..
Google would not have made this mistake in a beta ..

Bug found on this system.
OS: Win 7
IE version: 8.0.7600.16.385
opdateversion: 0

Just try another web browser. They are still many good web browsers available like: Mozilla Firefox, Google Chrome, Safari and Opera that conform web standards.

I agree with Alexander Hartl, this is Microsoft Internet Explorer bug. If you want to fix it, ask Microsoft to release Internet Explorer source code, LoL...

For what you use a web browser that make their own standard?

You can take Acid3 test here http://acid3.acidtests.org/
Internet Explorer scores the lowest of all major web browsers.

[Aditya Suseno (aditya-suseno)]

For those of you who can only use Internet Explorer installed on your campus PC. I have solutions:

• Ask your campus IT admin to install alternative web browsers like Google Chrome, Opera or Mozilla Firefox. Tell them that they are many good web browsers rather than Internet Explorer.
• If you can't ask or they refused your request. Install alternative web browser on your USB drive. As far as I know, Mozilla Firefox can be installed on USB drive. Just search for Mozilla Firefox portable edition.
• If you can't plug-in your USB drive on campus PC, then you are dead man! Maybe you should try another file hosting services.

Hope that it will works!

FWIW, we are working towards fixing this problem.

@Aditya Suseno :

We all know for shure that IE is a very buggy browser, o.k. so far ..

But if you want or have to share files with people in public you can not do discussions with every one who is not that clear about this (well, most of the time i do ;) ).
IE is still used a lot, i am very sad about that, but at this time we still have to live with it and to work around the issue .. - if the service is intended to be usefull for people

I did a Testdrive with the Ubuntu One sharing option with public files and, voila, i am here because of this ..

IE does not understand deflate (zlib) encoding used by updown (files.one.ubuntu.com) and S3 storage, however all other browsers announcing deflate support are OK.

During my tests if gzip is selected as content-encoding method then IE starts downloading/displaying the files correctly, which is actually strange.

So the temporary solution might be to start serving files with gzip content-encoding for browsers having MSIE in their User-Agent, this will not be the best solution but that will work for the time being.

I believe that inability to download files completely is worse than being able to download them but lying to the offending browser about content-encoding.

The code to output proper gzip stream to browsers that support gzip has landed in production. From now on all files will be served as compressed as gzip in case browser advertises gzip support.
I am marking this as Fix Released since the solution by James does not involve any hacks and will work properly with all browsers.

Thanks,

I will see how it goes. Earlier contribution about the (de)merits of
browsers are less relevant for those "publishing' to the larger
audience. We do not control the browser they use, a solution from our
side (even if it might not be technically beautiful) is preferred.

Thanks again.
