Thanks for the report.
/var/lib/pgadmin does not appear anywhere.

Summary: Cannot start pgadmin4 => Cannot start pgadmin4; missing dependency for python3-simplejson; missing /var/lib/pgadmin?

FWIW, this has already been fixed for cauldron in the meantime: http://svnweb.mageia.org/packages/cauldron/pgadmin4/current/SPECS/pgadmin4.spec?r1=1659294&r2=1730112
Although it would still need to be backported to 8.


As an interim workaround, this should make it work (run as root):

groupadd -r pgadmin
useradd  -g pgadmin -s /bin/false -r -c "pgadmin4" -d /var/lib/pgadmin pgadmin
mkdir -p /var/lib/pgadmin/{sessions,storage}
chown -R pgadmin:pgadmin /var/lib/pgadmin

I did succues to get it.
The process was:
groupadd -r pgadmin
useradd  -g pgadmin -s /bin/false -r -c "pgadmin4" -d /var/lib/pgadmin pgadmin
mkdir -p /var/lib/pgadmin/{sessions,storage}
chown -R pgadmin:pgadmin /var/lib/pgadmin
urpmi python3-psycopg2
urpmi python3-py-bcrypt
urpmi python3-flask-gravatar
urpmi python3-flask-security
urpmi python3-sshtunnel
urpmi python3-paramiko
urpmi python3-sqlparse

then I started as:
/usr/bin/python3 /usr/lib/python3.8/site-packages/pgadmin4-web/pgAdmin4.py

But I think somewhere by RPM database was maybe corrupt as I also tried to install package from cauldron but it required python3.9

Checked my configuration, found the user and group and files and access rights as you described in Comment 5 OK.
Checked the list of packages and found I missed
python3-psycopg2
python3-py-bcrypt
python3-flask-gravatar
but on trying to install these from MCC I get:

As this is on my daily working desktop, I surely will not draw in anything from cauldron.

I didn't install anything from cauldron, did you tried to remove the package that cause conflict ?

This is where I am, trying to install pgadmin4...  I seem to be going in circles with these dependencies...  pgadmin4 won't install on Cauldron either (bug 30373).

$ urpmi pgadmin4

urpmi pgadmin4 --test output in text file

Not using this software and not wanting to add so many packages to my 64-bit mga8 installation, I ran 'urpmi pgadmin4 --test' and attach the output, fwiw.

CC: (none) => rolfpedersen

@Pierre the original problem of the reporter seems a little bit different to yours. Rolfs output is on a clean MGA8 system without tinkered permissions/tweaks/alterations whatever. I can create also Rolfs behaviour here on a clean MGA8 installation.

Did you already try to remove python3-py-bcrypt as this is no dependency for pgadmin4 and clearly conflicts with pgadmin4 installation? By following the recommendation in comment 5 (which seems to be for slightly different issue than yours) you seem to have borked your MGA8 pgadmin4 installation.

There is no doubt, that there is a real issue in cauldron atm to install pgadmin. But for that you have already bug 30373

Actually, there's rogress...

urpmi pgadmin4

Finally installed pgAdmin4; but...  now, I have to figure out how to get around firefox insisting on secure connections; or how to secure pgAdmin4's port so that firefox doesn't refuse to connect.

For Firefox maybe this helps: https://support.mozilla.org/en-US/kb/https-only-prefs#firefox:linux:fx91

Thanks; but already had to do this months ago...  I've also been through the about:config settings; still no luck though...  
Just tried "links http://localhost:5432" - it returns:
 Error: Unable to retrieve http://localhost:5432 : Error reading from socket

lynx returns:
 Unexpected network read error; connection aborted.

Konqueror returns: 
  This page isn’t working
  localhost didn’t send any data.
  ERR_EMPTY_RESPONSE

Looks like I'll be spending some time with wireshark to make sure the connection is http and see what the exchange is...

Got it working.

pgadmin4-4.22-3.mga8 has the following problems.
/var/lib/pgadmin/ and
/var/log/pgadmin/ must be created and
chown apache:apache /var/lib/pgadmin and
chown apache:apache /var/log/pgadmin

The following packages need to be installed. They should be added to the
list of packages required by pgadmin4 ...
python3-psycopg2
python3-flask-gravatar
python3-sqlparse

Successfully loaded the pgAdmin page using http://localhost:5050/browser/
in firefox.

Pierre, note port 5050, not 5432. Found using
# netstat -tlpn|grep python3
tcp        0      0 127.0.0.1:5050          0.0.0.0:*               LISTEN      38165/python3

CC: (none) => davidwhodgins

Hmm...  changed ownership on those two directories. Packages were already installed.
$ netstat -tlpn
tcp        0      0 127.0.0.1:5432   0.0.0.0:*   LISTEN      3862132/postgres    

port 5050 never shows up; BTW, it's listed as:
$ grep 5050  /etc/services 
mmcc            5050/tcp                # multimedia conference control tool
mmcc            5050/udp                # multimedia conference control tool
so guessing you chose that port...?

Opened both ports in the firewall; but only ever see 5432 (postgres)

pgAdmin4 whines if browser is already running...

I get this whether firefox is already running, or not:
$ pgAdmin4 &
[GFX1-]: glxtest: X error, error_code=1, request_code=155, minor_code=1
[GFX1-]: glxtest: process failed (exited with status 1)

Yesterday, I was getting pgAdmin4's Configuration panel where I set the port to 5432; now that all seems installed, no Configuration is presented.  I probably need to specify "--new-window" as well as change the port number in the config file; but cna't find it...

Ah...  just found /usr/lib/python3.8/site-packages/pgadmin4-web/config.py which contains:
DEFAULT_SERVER = '127.0.0.1'
DEFAULT_SERVER_PORT = 5050

While pgAdmin4 appears to be running, no port 5050...  All I get is:

$ pgAdmin4 &
[1] 3951471

I must be missing something basic...

* postgresql is running on port 5432
* as normal user: pgAdmin4 &
* browser is invoked with "localhost:5432"
* change port to 5050; still unable to connect...

I started it with "systemctl start pgadmin4.service". No modifications to
any files provided with pgadmin4 after installing the package.

Hi Dave,
Is all tree from /var/lib/pgadmin owned by apache:apache?
Is /var/log/pgadmin created at installation?

CC: (none) => yves.brungard_mageia

I created /var/lib/pgadmin and /var/log/pgadmin and changed those two
directories to be owned by apache. That should have been done during the
install of pgadmin4 with a file in /usr/lib/tmpfiles.d/, but wasn't.
# ls -ld /var/lib/pgadmin /var/log/pgadmin
drwx------ 4 apache apache 4096 Jul  2 14:41 /var/lib/pgadmin/
drwxr-xr-x 2 apache apache 4096 Jul  2 14:32 /var/log/pgadmin/

Once those two directories were manually created and changed to be owned
by apache, I was able to start pgadmin4.service. It then created files
and directories in those two directories. Those files/directories are
owned by apache:apache.

See this report: https://bugs.mageia.org/show_bug.cgi?id=30385
A new build is to test.

Seeing updates come through; but nothing for this report. What should I be looking for?

Closing as a duplicate of bug 30385 where it's being fixed. Please see that
