The Archive_Tar PHP extension must be installed before the PKP PN can be enabled

[joapreditor]

Hello,

I am using OJS 3.2.03. I have installed PKP PN plugin from plugin gallery. Its setting shows an error message “The Archive_Tar PHP extension must be installed before the PKP PN can be enabled”. I have gone through few of the posts in the forum. However, could not figure out. Service provider has confirmed that Archive tar is installed in server.
I am not an IT expert. I request all of you to guide me from scratch. I am also sharing php error log in case you need it

Hi @ joapreditor
The Archive_Tar php extension is not same thing with Unix tar executable, but as far as I know, they have a common function; uncompressing tar archives. The existance of unix tar executable doesn’t mean that Archive_Tar extension is installed and you may use it.

There is another discussion here about this extension. I don’t have much time to read, but I hope it helps you.
Regards.

PKP PLN Plugin ask for Archive_Tar PHP extension

Hi, I’ve just upgraded my OJS from 2.4.7.1 to 2.4.8.0 specifically to use the PKP PLN Plugin. Unfortunately, from the the plugin setting page I get this message: The Archive_Tar PHP extension must be installed before the PKP PLN can be enabled. I’m quite sure to have corrected installed PEAR and the Archive_Tar in the server. Digiting “pear list” from Linux shell I get: Installed packages, channel pear.php.net: ========================================= Package Version State Archiv…

Hi again,
This error information seem to be helpful for explaining why your OJS can’t execute tar executable.

[01-Jun-2020 21:48:23 Asia/Kolkata] PHP Warning: file_exists(): open_basedir restriction in effect. File(/bin/tar) is not within the allowed path(s):

open_basedir restriction limits the files that can be accessed by PHP to the specified directory-tree, including the file itself. This directive is NOT affected by whether Safe Mode is turned On or Off.
Therefore, until php.ini settings are properly configured by the server administrator, you will not be able to use such commands, though they are installed on the server.
That means, either that restriction should be disabled, or properly configured.
regards,

open_basedir restriction in effect. File(/) is not within the allowed path(s):

Thanks a lot @drugurkocak.

Your replied helped people from service provider to identify issue and they modified something and now PKP PN is depositing issues to LOCKKS.

Status of plugin shows like this

Is it working fine? Processing and LOCKKS status are unknown and Complete is No.

Thanks a lot

Hi @joapreditor,

This looks promising – I’d suggest watching it for a couple of days, as it’s a periodic process!

Thanks a lot @asmecher. Will inform you and @drugurkocak about the happenings in a few days

[dodi1985]

it is ok @asmecher?

[asmecher]

Hi @dodi1985,

Yes – the relevant column is LOCKSS Status. A status of “Agreement” means that the content (issue ID #1) has been ingested into the LOCKSS network and all nodes agree on the content that’s archived there.

thank you @asmecher, hopefully, the deposit can be executed in the near future.

Hi, I had just the similar problem with message “The Archive_Tar PHP extension must be installed before the…” After long search I had found following manual - Manual :: Checking if PEAR works - it helped - problem was in missing inclusion of path to pear. There are two different places where it has to be included in Ubuntu.
