file-roller cannot decompress non-archive .gz

Thank you for reporting this issue and trying to make Ubuntu better... Could you please post either

A) A screen snap of the error
B) A cut-and-paste of the error itself...

This will help us to track down and solve your problem

Thanks

* Marking incomplete pending enough information to complete triage

I previously noted that a dialog appears with "An error occurred while extracting files.". I have now attached a screenshot of the error as well, after choosing the "Extract Here" option of the file you see on the desktop. If you have an Intrepid system, are you able to reproduce the issue as described? Thanks for the triage :-)

Please leave the status as incomplete as it shows it is being worked on by a triager... From here I will either set the status to invalid or triaged...

Are you able to un-archive the file using gzip from a terminal?

in a terminal type gzip -d <filename>

yes

I wrote the following (and attached) shell script to see if I could reproduce
the problem in Ubuntu 8.04 (file-roller version 2.22.3-0ubuntu1):

    #!/bin/sh
    FILE=$(tempfile)
    echo Hello world >$FILE
    gzip --to-stdout $FILE >$FILE.gz
    tar --create --gzip --directory=$(dirname $FILE) $(basename $FILE) \
        >$FILE.tar.gz
    file-roller $FILE.gz &
    file-roller $FILE.tar.gz &

I can’t reproduce the bug in Ubuntu 8.04. However, if I’ve understood the
report correctly (and have not messed up!), then this script should reproduce
the bug on affected systems: file-roller should succeed in opening
$FILE.tar.gz, but fail to open $FILE.gz. If I’ve misunderstood the report,
then please explain how, or feel free to come up with a different test!

It's important to note that this occurs on Ubuntu 8.10 Intrepid (with file-roller 2.23.3-0ubuntu2), not Ubuntu 8.04LTS Hardy.

file-roller can open the file just fine. The problem occurs when extracting. Your shell script opens file-roller for both files successfully, but does not attempt extraction.

If I extract (double click) the file in the window containing the .tar.gz file, it correctly extracts the "Hello world" file.
If I extract (double click) the file in the window containing the .gz file, it produces the error.

Well, how about this, then? (I’ve taken the opportunity to add in some
quotation marks to make the script just slightly more robust!)

    #!/bin/sh
    FILE="$(tempfile)"
    echo Hello world >"$FILE"
    gzip --to-stdout "$FILE" >"$FILE.gz"
    tar --create --gzip --directory="$(dirname "$FILE")" "$(basename "$FILE")" \
        >"$FILE.tar.gz"
    file-roller --extract-here "$FILE.gz" &
    file-roller --extract-here "$FILE.tar.gz" &

That script doesn't work, but manually adding the --extract-here part reproduces the issue.

I've already thoroughly documented this problem, which makes it clear the issue is independent of whether or not you're doing this with a shell script. This should be easily reproducible by anyone with Intrepid. It would be most useful if someone else could confirm this issue on Intrepid to assist with the triage of this issue. Thanks.

Please leave the status as incomplete as a triager is still dealing with the issue. The bug will either be confirmed or invalidated as a result based on what we investigate.

Thanks,

Richard Seguin

Hew, I'll install Intrepid in a VM and get back to you on this issue

Confirmed fixed as of file-roller 2.23.5-0ubuntu1
