Regression: Ark unable to extract or view 7z after p7zip to 7zip transition in noble

[theofficialgman]

Ark is unable to extract or view 7z after p7zip to 7zip transition in Ubuntu noble 24.04

I assume ark relied on /usr/lib/p7zip/7zr which is now gone in 7zip

Its been almost a month with no activity. This bug still exists.
Please have this fixed before release.

[theofficialgman (theofficialgman)]

issue is still present in the new 4:23.08.4-0ubuntu1 ark release

[Scarlett Gately Moore (scarlettmoore)]

Looking into it. Sorry I have only been back a few weeks and I still have many bugs to catch up on!

[Scarlett Gately Moore (scarlettmoore)]

Now moved upstream. https://bugs.kde.org/show_bug.cgi?id=468240

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[theofficialgman (theofficialgman)]

Can we get the upstream commmit that fixes unencrypted 7z support backported please? https://bugs.kde.org/show_bug.cgi?id=468240#c13

Bug still in 4:23.08.5-0ubuntu5

this patch https://github.com/KDE/ark/commit/0d7d7b6558475897a06b0b315b45000f7ae0597a is also needed

[Scarlett Gately Moore (scarlettmoore)]

These patches don't apply to qt5... asking upstream for a backport.

[Xu Zhen (xuzhen666)]

The patch at https://bugs.kde.org/show_bug.cgi?id=468240#c13 is for libarchive plugin, but even without it, ark can directly execute 7zip program to read and decompress 7z files.

It's just because the output text of the 7zip program in the repository has changed, causing ark to not recognize it and therefore unable to view or decompress.

The patch I mentioned at #8 is enough for this issue. I have tested it with 23.08.5-0ubuntu5

[Shy Zedaka (shaytzedaka)]

with both p7zip (16.02+transitional.1) and 7zip (23.01+dfsg-11) packages installed in Kubuntu 24.04
i am unable to open and view any 7z file using Ark (23.08.5)

i've updated the system to the latest updates.

I uploaded the patched package to my PPA: https://launchpad.net/~xuzhen666/+archive/ubuntu/bug2051041/
