gencache_init: Failed to create directory: /var/www/.cache/samba - Permission denied

Thanks for reporting this issue and flagging the related bug report. That report details these steps to reproduce on redhat:

- Steps to Reproduce:
1. Create a share on Windows AD server.
2. Join a system to AD domain via realmd (samba + winbind)
3. Try to access the share hosted on Windows system via smbclient

- Actual results:
'smbclient' command shows an error/warning while accessing the share as non-privileged user e.g. local linux user.
---
gencache_init: Failed to create directory: /home/localuser1/.cache/samba - No such file or directory
---

- Expected results:
'smbclient' command shouldn't throw any error while accessing the share as non-privileged user.

Do these exact steps reproduce the issue for you on Ubuntu 20.04? Did you use the workaround of doing 'mkdir ~/.cache' to resolve things locally, or did you take a different approach?

The solution for the bug report you mentioned is the patch I've attached here.

From looking at the focal source for samba, it appears this patch is already included when security provided an update to version 4.13.14, last November.

What version of Samba do you have installed? Does the issue resolve when you update to 2:4.13.17~dfsg-0ubuntu0.21.04.1 or newer?

I did create the temp dir and the solutions fixed the issue.

Thank you for the follow up, Andrea. Can you confirm the version of Samba you have installed there? We want to make sure whether this bug is present in the latest Samba version or not. Thanks.

Hello i have ^Croot@nextcloud:~apt install smbclient

smbclient is already the newest version (2:4.13.17~dfsg-0ubuntu0.21.04.2).

Im sorry for the really late response

No problem and thanks for the feedback, Andrea.

Since the bug seems have been fixed in the version currently available, I am marking this bug as Fix Released. Feel free to reopen it if you think the bug is still valid.

Thanks.

Would that be version (2:4.13.17~dfsg-0ubuntu0.21.04.2) ? Because I'm still having this issue on version (2:4.13.17~dfsg-0ubuntu0.21.04.2)

I'm still having this issue on version (2:4.13.17~dfsg-0ubuntu0.21.04.2)

Hello Andrea,

I double checked the source code of version 2:4.13.17~dfsg-0ubuntu0.21.04.2 and the directory_create_or_exists_recursive() call in gencache.c is there, so the patch that is reported fixing the redhat bug is applied on the Focal package.

You could be hitting a slightly different case, but in this case to proceed with the investigation we need a set of steps to reproduce the issue from a clean Focal system. Could you please try to identify such steps and share them with us?

As we're waiting for more information I'm leaving this report as Incomplete for now.

Thanks!
