ls /tmp/oc_tmp_56egK8-folder/news/vendor/bin/

picofeed

Have noticed the same in the past but completely forgot to report it here. It seems this is caused because the vendor/bin/picofeed is a symlink to vendor/fguillot/picofeed/picofeed

[BernhardPosselt]

I guess the install/update script does not remove symlinks proplery

[ghost]

@paroj Btw. are you able to update the news app via the GUI at all? I'm still having the issue described in #18391 so just wondering if you're also facing the same issue?

[paroj]

the update itself succeeds - I just have to remove the /tmp/oc_tmp_56egK8-folder/news/vendor/bin/ folder manually afterwards

@VicDeo

[VicDeo]

yep. This will unlink target and not symlink itself.
https://github.com/owncloud/core/blob/stable9/lib/private/helper.php#L227

So there will be two notices:

• while unlinking non-existing target. it is already unlinked due to $fileInfo->getRealPath(). But it depends on the order of filesystem items iterator returns so happens from time to time.
• while rmdir on symlink parent directory

just as per #24478

Error PHP rmdir(/tmp/oc_tmp_0oiTQP-folder/news/vendor/bin): Directory not empty at /var/www/owncloud/lib/private/helper.php#225 2016-05-04T18:15:01+00:00
Error PHP unlink(): No such file or directory at /var/www/owncloud/lib/private/helper.php#227 2016-05-04T18:15:01+00:00

[VicDeo]

@PVince81 should be fixed in master with #24899
Backport changes in helper.php only?

[PVince81]

Fix is here #25255

[Pazu]

Sorry to post in an old issue, but I've seen these messages in my log for a long time and still see them after upgrading to 9.1.1. Shouldn't these be gone as of 9.1 if this is fixed?

rmdir(/tmp/oc_tmp_XS146u-folder): Operation not permitted at /home/foo/public_html/lib/private/legacy/helper.php#218

According to my shared hosting provider:

the RM errors are not related to anything with ownCloud. you dont have access to TMP and its not needed for ownCloud

[ghost]

@Pazu I think this is unrelated to this issue here. The issue discussed here was about the symlink which wasn't removed correctly caused the posted error in the initial report.

Your issue / error is different and is caused by your environment setting the /tmp folder as a temp directory for PHP. where ownCloud has no access to. For further support please use https://central.owncloud.org

[VicDeo]

@Pazu you can create a dedicated tmp for your owncloud, e.g. /home/foo/tmp and tempdirectory in config.php to use it:
