RevPi Core 3+: no Pictory, error 403 in browser

[etienne1984]

Hello,

We bought and configured a first RevPi Core 3+, and it worked without major problems.
We had a second piece (or ordered recently I am not sure), I configured it as the first one:

- apt update/upgrade until no more updates available
- try to access http://XX.XX.XX.XX to view Pictory interface

On this RevPi Core 3+, we have a "403 forbidden" message.

Code: Select all

pi@RevPi39037:~ $ cat /var/log/apache2/error.log
(...)
[Mon Nov 15 12:25:17.825373 2021] [autoindex:error] [pid 1609] [client 10.121.78.150:58726] AH01276: Cannot serve directory /var/www/: No matching DirectoryIndex (index.html,index.cgi,index.pl,index.php,index.xhtml,index.htm) found, and server-generated directory index forbidden by Options directive

and we have that:

Code: Select all

pi@RevPi39037:~ $ ll /var/www/

drwxr-xr-x 12 root     root     4096 Nov 15 09:14 revpi

Which is quite different from the other unit, the one properly working, which has:

Code: Select all

Any idea? Did we miss something obvious...?

Thank you for your help,

Hi etienne,

can you please share the installed image version of both devices? This can be fetch with the following command: cat /etc/revpi/image-release

Nicolai

[etienne1984]

Of course:

Code: Select all

pi@RevPi39043:~ $ cat /etc/revpi/image-release
2020-03-02-revpi-stretch.img

and:

Code: Select all

pi@RevPi39037:~ $ cat /etc/revpi/image-release
2020-03-02-revpi-stretch.img

Could updates have an impact on apache files ???

It is as if files have been moved to /var/www/revpi folder, on working unit I have:

Code: Select all

pi@RevPi39043:/var/www $ ls -la

If I try to browse http://XX.XX.XX.XX/revpi/ on problematic unit, I have an orange portal (rather than red one), and I cannot use usual "admin" "label-password" credentials.

Is this normal ?
Thank you for you quick reply and help.

Hello EdS,

as the "apt update&apt upgrade" getting executed, the pictory (and revpi-webstatus) are upgrade from 1.x to 2.x. The version 2.x contains following changes:
1. the DocumentRoot of pictory web application changed from /var/www/ to /var/www/pictory
2. the tcp port of the pictory is changed from 80 to 41080, but it will be automatically redirected when the 80 (by default) is used.
3. the color of GUI is changed from red to orange.
more info: https://revolutionpi.com/tutorials/rele ... rect=en_US

Regarding to you case, I think following things might be needed to check:
1. reboot after upgrade of pictory/webstatus, to make the apache2 reload the configuration .
2. clear the cache of the browser of client to make the new changed be used.
3. if it still not works, try to check the status of apache2 with command "systemdctl status apache2", it should be in active.

Hi everyone. I have the same problem . After apt-get update/upgrade I can't access pictory by typing the IP-Address of RevPi in my browser.
I've been able to get the login screen than typing http://ip-address/revpi but it doesn't accept the password.
Also it shows this error on page load:

Code: Select all

Error in AjaxGetJSON: Not Found

Browser Console:


Now i'm stuck and can't configure my plc for the project i'm working on.

[etienne1984]

Hello,

Thank you Simon for answer. Unfortunately, it did not resolved the problem:

1. I already had restarted my revpi several time (I did it again, no change).
2. I cleared browser cache (used private session), no change except I also have a popup with the error mentioned by nicolai hereabove ("Error in AjaxGetJSON: Not Found").
3. Apache is running (I checked with systemctl as required, but you may find in my previous message apache logs appearing upon HTTP requests, and I have also access through http://XX.XX.XX.XX/revpi/ (and not http://XX.XX.XX.XX/pictory) to an orange portal, but cannot login with my credentials.

Please can you help further ?

I attached some apache configuration file (in /etc/apache2). You also have my file tree in /var/www in messages above, tell me if you need more.

Hello,

I will check it on my devices and go back as soon as I get something.

Hi everyone,

unfortunately this is a regression of a recent fix. We're aware of this and working on a solution which we hopefully can publish later today. I'm sorry for any inconvenience!

For now please try to downgrade to the previous version with the following command:

Code: Select all

sudo apt install pictory=1.4.7 revpi-webstatus=1.2.10

Nicolai

[etienne1984]

Hi all,

OK, I downgraded as you propose, it seems to work without problem.

Luckily, I was anticipating this revpi configuration step for my part, so I am not in a hurry. I will wait for your fix, in order to process my device configuration from the updated version you are about to publish. Please keep us informed, thank you,

Etienne

[nicolaiB]

Hi Etienne,

you can safely proceed with your device configuration. There is no change in the configuration format even with the upcomming patch release. Of course I will let you and the community know as soon as the new package is published!
