Thread: Cannot Run pgAdmin4 v8.13 on AlmaLinux 8 after upgrade from v8.12

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:

mod_wsgi (pid=3535715): Failed to exec Python script file '/usr/pgadmin4/web/pgAdmin4.wsgi'.
mod_wsgi (pid=3535715): Exception occurred processing WSGI script '/usr/pgadmin4/web/pgAdmin4.wsgi'.
Traceback (most recent call last):
ImportError: no pq wrapper available.
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:

The primary concern is at undefined symbol: PQchangePassword

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

Regards,
ayrus02

Is libpq5 installed on your system?

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,

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,

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.

This looks fine.

What's the output of pg_config ? 

And below are the output of dnf list libpq5* on my AlmaLinux 9 (x64) machine:

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:

mod_wsgi (pid=3535715): Failed to exec Python script file '/usr/pgadmin4/web/pgAdmin4.wsgi'.
mod_wsgi (pid=3535715): Exception occurred processing WSGI script '/usr/pgadmin4/web/pgAdmin4.wsgi'.
Traceback (most recent call last):
ImportError: no pq wrapper available.
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:

The primary concern is at undefined symbol: PQchangePassword

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