Internal server error when opening "settings" when Webdav password set (v7.1.5)

Hi

Since the update form 7.0.5 to 7.1.3, the “settings” page doesn’t work anymore when a user previously had set an Webdav password. If the user didn’t set one, the settings page works fine.

Error log:

Still getting the error on 7.1.4:

Does anybody have an Idea?

Any update on this?

Still the same Error in 7.1.5:

I guess you did not remove fastcgi in seafdav.conf.

andrin · November 3, 2020, 3:14pm

It is disabled. My config looks like this:

[WEBDAV]
enabled = true
port = 8080
fastcgi = false
share_name = /webdav

Pretty identical to the documentation (SeafDAV - Seafile Community Manual)

casselt · November 3, 2020, 3:34pm

You need to remove the line, not disable it. The documentation you linked is not the official one.

Take a look at the official documentation:

https://download.seafile.com/published/seafile-manual/extension/webdav.md

andrin · November 4, 2020, 10:07am

Yes sorry that was the wrong manual. I removed the line and restarted the services:

[WEBDAV]
enabled = true
port = 8080
share_name = /webdav

However the error is still present (seahub log):

Looking closer, the error states that it cannot find AES. Did you install cryptography as stated in https://manual.seafile.com/deploy_pro/adfs/?

sudo pip install cryptography

andrin · January 7, 2021, 2:17pm

Yes it is installed:
[root@localhost ~]# pip3 install cryptography Requirement already satisfied: cryptography in /usr/lib64/python3.6/site-packages (2.3) Requirement already satisfied: idna>=2.1 in /usr/lib/python3.6/site-packages (from cryptography) (2.5) Requirement already satisfied: asn1crypto>=0.21.0 in /usr/lib/python3.6/site-packages (from cryptography) (0.24.0) Requirement already satisfied: six>=1.4.1 in /usr/lib/python3.6/site-packages (from cryptography) (1.11.0) Requirement already satisfied: cffi!=1.11.3,>=1.7 in /usr/lib64/python3.6/site-packages (from cryptography) (1.11.5) Requirement already satisfied: pycparser in /usr/lib/python3.6/site-packages (from cffi!=1.11.3,>=1.7->cryptography) (2.14)

However, PyCrypt was not installed, after installing PyCrypt /profile worked again:
yum install gcc gcc-c++ python3-devel pip3 install pycrypto
