Re: [SOLVED] Re: Cannot Run pgAdmin4 v8.13 on AlmaLinux 8 after upgrade from v8.12 - Mailing list pgadmin-support

Hi,

I just want to share that the problem with my installation of pgAdmin4 on my AlmaLinux v8.x and v9.x are now can run with Web mode using Apache HTTPD.
I will try to explain how I overcome the problem

1. First, the error log of my pgAdmin4 are like below

mod_wsgi (pid=3540264): Failed to exec Python script file '/usr/pgadmin4/web/pgAdmin4.wsgi'.
mod_wsgi (pid=3540264): Exception occurred processing WSGI script '/usr/pgadmin4/web/pgAdmin4.wsgi'.

Attempts made:
- couldn't import psycopg 'c' implementation: /usr/pgadmin4/venv/lib64/python3.9/site-packages/psycopg_c/pq.cpython-39-x86_64-linux-gnu.so: undefined symbol: PQchangePassword
- couldn't import psycopg 'binary' implementation: No module named 'psycopg_binary'
- couldn't import psycopg 'python' implementation:

2. From the log I know that after upgrading from pgAdmin4 v8.12 to v8.13 and above, it require some psycopg_binary python package

3. So I open the pgAdmin4 virtual environment using command:

source /usr/pgadmin4/venv/bin/activate

4. Then run PIP to install the required package psycopg_binaryby running command:

pip install "psycopg[binary]"

5. And restart the Apache HTTPD, and access it from web browser.

That's it, I can access my instance of pgAdmin4 v8.13 or the latest v8.14 from web.

Hi,

For this problem is it already identified the main problem? is it a bug on the new release v8.13?
Is there any hint how to solve the problem? until now, I still cannot upgrade to v8.13 because of this problem

Please try moving libpq.so and libpq.so.5 to the other location and keeping only one libpq `/usr/lib64/libpq.so.5.17`.

Hi,

Make sure that your libpq is located at LIBDIR = /usr/lib64. This error may occur when you have multiple libpq installed on your system. Also do not forget to restart the apache server.

Thanks,

This looks fine.

What's the output of pg_config ?

Hi,

I've upgraded the libpq5 to version 17.0-43PGDG.rhel8
I've also restart the apache server.

What's the output of `yum list libpq5*` ?

But the problem still exist. With the same error in log file.

I've also can confirm that this also happened on my other server running AlmaLinux 9 (x64).
My other server also has libpq5 with version 17.0-43PGDG.rhel9 and also running as Web Mode via Apache.

Hi Vashi,

Yes, I can confirm it is installed with version:
libpq5.x86_64 - v16.3-43PGDG.rhel8

During the pgAdmin upgrade on your system, the libpq5 should have been upgraded to the latest (v17), which didn't happen in your case.

Can you please upgrade libpq5 to the latest version? It should fix this issue.

Thanks,

Khushboo

Hi,

Today, I've upgraded my pgAdmin4 version from v8.12 to v8.13 using dnf on AlmaLinux 8.

My pgAdmin4 is installed as web mode and accessed via Apache.

After upgrading to v8.13, when I access the pgAdmin4 address from web browser, it give an error 500. When I look at the error log, it contains the line below:

- couldn't import psycopg 'binary' implementation: No module named 'psycopg_binary'
- couldn't import psycopg 'python' implementation:

The primary concern is at undefined symbol: PQchangePassword

Is there any bug or I have do the update wrongly?
