Dear @asmecher ,

we’re failing in getting the PKP PN Plugin to work. I found this post Regarding PKP PN Setting & Status and requested our hosting provider (we’re not hosting ourselves), which the correct path to tar is. We got /usr/bin/tar and I added it to config, but still all articles are pending.

In PKPPNDepositorTask-xxxx-xxx.log we still get:
[Warning] Your system must have a tar executable.

Do you have any ideas, what I could try to get the PKP PN Plugin to work?

Many thanks,
Tobias

In my case, the problem was solved by downgrading the PHP version to 7.3

Hi @twa,

What version of the PKP|PN plugin are you using with OJS 3.3.0-6?

Hej @asmecher and @aabahishti ,

we are running PHP 7.3.30 and PKP/PN v2.0.4.2 (28.07.2021).

Thanks,

Hi @twa,

Do you have the Archive_Tar PEAR extension installed in your system?
How did you install the PKP PN plugin?

@asmecher Thanks for answering (sorry for the delay – I was on holidays).

How did you install the PKP PN plugin?

With the plugin gallery of the OJS installation.

Do you have the Archive_Tar PEAR extension installed in your system?

Do I have to install this separately? And how do I do that?

Thanks
Tobias

Hi @twa!

Is the plugin working for you now? I’ve created an issue to avoid displaying this message: Remove the PEAR/Archive_Tar requirement · Issue #25 · pkp/pln · GitHub

Best,
