Description Patrick Silva 2017-12-18 00:55:39 UTC 
I'm trying extract a ZIP LZMA file created with 7zip on windows system using Ark 17.12 on Arch Linux.

I get the error
"Compression method not supported"
Comment 1 Elvis Angelaccio 2017-12-23 10:38:33 UTC 
Can you attach a test archive?

test archive
Comment 3 Christoph Feck 2018-01-01 17:52:42 UTC 
Cannot reproduce. ZIP from comment #2 opened and extracted fine using Ark, 688 files in 2.937.177 bytes extracted.
Comment 4 Elvis Angelaccio 2018-01-02 12:58:09 UTC 
IIRC only 7z (which is probably what Christoph is using as zip backend) can handle the LZMA compression method. 

If you disable the libzip plugin from the ark settings you should be able to extract the archive.

You are right. Just tested on neon dev unstable.
Comment 6 Patrick Silva 2019-03-24 12:32:02 UTC 
Still valid with ark 18.12.3 when libzip plugin is enabled in ark settings.
I don't get an error message anymore, but not all folders/files are extracted from the attached test file.

Operating System: Arch Linux 
KDE Plasma Version: 5.15.3
KDE Frameworks Version: 5.56.0
Qt Version: 5.12.2
Comment 7 Patrick Silva 2019-08-06 19:27:24 UTC 
I can't extract the file from comment 2 with Ark 19.08 RC on Arch Linux even after disabling libzip plugin in Ark settings.
Comment 8 2wxsy58236r3 2020-04-03 04:25:00 UTC 
Do you have Info-zip installed (pacman -Syu unzip) and its plugin enabled in Ark?

unzip should be able to handle this kind of archive.

info-zip is enabled in Ark settings but Ark can not extract all content from the test archive in comment 2 and shows no error message. Attached screenshot shows the amount of files/folders inside test archive and extracted by Ark.
Ark 20.07.70 on Neon unstable edition.
Comment 10 Patrick Silva 2020-04-03 10:47:00 UTC 
if libzip plugin is disabled, all content of archive is extracted.
Current situation could result in data loss if the user deletes the archive
before checking if its content was correctly extracted.

Forward errors from archive interface when batch-extracting

Errors from ExtractJob are not handled when called as a subjob of
BatchExtractJob. This can result in silently failing extractions.

The latest git master of libzip should now be able to handle the LZMA compression method.
