Topic: 'Internal server error accessing ' iredadmin/system/log?*

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 0.9.9
- Deployed with iRedMail Easy or the downloadable installer? No
- Linux/BSD distribution name and version: CentOS 7.7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Apache
- Manage mail accounts with iRedAdmin-Pro? No
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

I refer to this post as representing the same issue that I have.
iRedAdmin-Pro Support Post

My log /var/log/messages
Showing 200 response for system/log and 500 response when a QueryString is added.

Unfortunately the fix includes "easy_install web.py==0.40.dev1".
I am not using easy_install, so I do not have access to the updated code.

I am happy to perform the steps described if I can get the new version.

For reference, these are the versions of the python packages referred to in the other post.  Both were already installed.

Re: 'Internal server error accessing ' iredadmin/system/log?*

With package "python-setuptools" installed, you should have command "easy_install" available.
Run "easy_install web.py" should install the latest web.py 0.40 for you (btw, i'm now one of the web.py maintainers and i tagged this 0.40 release days ago), then restart "iredadmin" service.

Oh, wow.  Clearly I know nothing of the Python eco system.
I was confused that "iRedMail Easy" and "easy_install" were the same.

I ran this:

and restarted iredadmin (I'm using the Apache mod_proxy_uwsgi)

systemctl restart iredadmin

But refreshing the iredadmin page and clicking the link in the "Admin" column still shows

internal server error

Given your update to the post, I tried the specifying the version.

But now iredadmin does not work at all.

iRedMail Easy is the name of our web-based deployment/upgrade/tech support platform. "easy_install" is a Python package manager. They're different things.

Is command "pip" or "pip2" available on your server? If yes, try it instead of "easy_install" like this:

pip install web.py==0.40

Re: 'Internal server error accessing ' iredadmin/system/log?*

No luck on the pip commands.

# pip install web.py==0.40
-bash: pip: command not found
# pip2 install web.py==0.40
-bash: pip2: command not found

It seems that the easy_install fails trying to install cheroot.  so I tried that by itself.

Try the previous stable release 6.6.0 instead of latest 7.0.0:

easy_install https://files.pythonhosted.org/packages/c7/2b/9d8f54399f1acd2c87a61d72de7018aeb7d4adfabb6c0ca1ff89c9d2b79b/cheroot-6.6.0.tar.gz

Re: 'Internal server error accessing ' iredadmin/system/log?*

OK, i got feedback from cheroot developers, the "easy_install" tool is out of date and not supported by cheroot. You have to install "pip" first, then install cheroot with pip:

easy_install pip
pip install cheroot

After installed web.py 0.40, did you restart Apache service? (If you're running Nginx, you should restart "iredadmin" service instead)

I have not restarted Apache because I have updated the config to use the new iredadmin service on port 7791 as per this post.

    Alias               /iredadmin/static "/var/www/iredadmin/static/"
    ProxyPass        /iredadmin/static  !
    ProxyPass        /iredadmin "uwsgi://127.0.0.1:7791"

I did restart the iredadmin service
