Hi there,
I've been using KUbuntu for quite a long time now. I've migrated from 18.04 to 18.10, and now to 19.04, without any problem that I noticed, until now. Since I updated to 19.04, I can no longer decompress multi-volume ZIP files either using ark or unzip, while 7zip-full can decompress them fine. I've 18.10 in another laptop and can decompress them, too. No problem either on windows 10 with either standard explorer support, or 7zip.
This is the structure for the files:
file.zip.001
file.zip.002
file.zip.003
file.zip.004
This is what I get when I try to decompress with unzip:
$ unzip -Z file.zip.001
Archive: file.zip.001
Zip file size: 1521000000 bytes, number of entries: 21531
warning [file.zip.001]: end-of-central-directory record claims this
is disk 22438 but that the central directory starts on disk 36080; this is a
contradiction. Attempting to process anyway.
warning [file.zip.001]: 448404665 extra bytes at beginning or within zipfile
(attempting to process anyway)
error [file.zip.001]: start of central directory not found;
zipfile corrupt.
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)
1 archive had fatal errors.
This comes from unzip -Zv file.zip.001:
End-of-central-directory record:
-------------------------------
Zip archive file size: 1521000000 (000000005AA89E40h)
Actual end-cent-dir record offset: 1503402521 (00000000599C1A19h)
Expected end-cent-dir record offset: 1054997856 (000000003EE1FD60h)
(based on the length of the central directory and its expected offset)
This zipfile constitutes disk 22439 of a multi-part archive. The central
directory starts on disk 36081 at an offset within that archive part
of 1053957967 (000000003ED21F4Fh) bytes. The entire
central directory is 1039889 (00000000000FDE11h) bytes long.
44384 of the archive entries are contained within this zipfile volume,
out of a total of 21531 entries.
I tried using file.zip.004 in both cases, just in case, with the same issue.
This is happening with all files using the same format (these files are created from a backup tool), and whenever I had no problems before, I can not open, test, list or do whatever with them.
ARK tells this: Not a zip archive.
Tried re-installing unzip, libzip5, no luck. I did check on libzip's github for any issue about this, but seems to be something happening only to me!?
Can anyone give me a hand on this? I'm a bit puzzled!
