Thread: pgAdmin 4 not starting after upgrade to 6.4

Hi Dave Caughey,

I am not able to reproduce the issue.

How I tested:

1. Installed pgadmin4 6.2

2. Launch pgAdmin4

3. close pgAdmin4

4. Installed pgadmin4 6.4

5. Launch pgadmin4

6. No issue found

Can you please uninstall pgadmin4 from the control panel and try to install pgadmin4 6.4 again?

Hi all,

After upgrading from 6.2 to 6.4, when I start pgAdmin I get an 

"The pgAdmin 4 server could not be contacted" 

message, with the environment details shown below.

I have tried re-installing pgadmin4-6.4-x64.exe, and tried rebooting windows.

Should I uninstall some component and reinstall?  Or?  And if you need any logs, please let me know where to grab them.

Thanks,
Dave

But recent versions of pgAdmin *have* been running on Windows 7.  Over the years I've religiously updated throughout v4, v5 and v6 (up until v6.2) and it's been running perfectly fine up until I upgraded from v6.2 -> 6.4 yesterday.

And I've tried reinstalling v6.2, but I'm now getting the same error.  So clearly it's just a configuration issue or compatibility issue with some other component (e.g., python 3.8) because it was able to run yesterday.

But looking back through my email history, I see I did have a problem updating to v5.0, that Dave Page kindly resolved.  I don't know if what I'm now experiencing is the same issue, but is there a similar work around, given that v6.2 was working perfectly fine yesterday?   I'd be happy to freeze at v6.2, if that's really the last version, but please don't make me go back to v4.30!

Dave

But... pgAdmin v4.30 runs fine.

So I believe the issue is that Python 3.9 has dropped support for Windows 7 and earlier, something which I for one didn't realise until I started looking into this (see https://www.python.org/downloads/windows/).

I've kicked off a build using Python 3.8 for testing. That claims to support back to Vista. I'll send a link once it's done.

Here's the Python 3.8 based test build. Note that I haven't tested it at all - I just kicked off the normal build process but told it to use 3.8 instead of 3.9.

https://developer.pgadmin.org/builds/2021-02-25python38-1/pgadmin4-5.0-x64.exe

Please let us know if it works on Windows 7.

Dave told me offlist that it's working for him.

So, we need to think about how long we'll support Windows 7. Sooner or later we will have to update Python... :-(

Dave

Yes - we stopped officially supporting Windows 7 with 4.30, but later rolled back the Python version so it would continue to work regardless. We recently had a round of updating the Python versions across the board, and I'll be honest, I completely forgot about the Windows 7 compatibility when we did that. Unfortunately though we really can't stick to an old version any longer; the longer we do so, the harder it becomes to update it later.

So I'm afraid if you're using Windows 7, you'll need to freeze at v6.2. 

 

Cheers,
Dave

I can live with freezing at 6.2.

But... it won't run either, because I'm assuming it relies on Python 3.9.  We know it runs successfully with 3.8, but I'm guessing the installer is trying to install 3.9.

Is there any way I can get a one-off 3.8 build... and then I'll never bother you again ;-) ?  Or is there some other post install fix?

And as an aside, shouldn't the installer check for OS compatibility?  E.g., if you can't support Windows 7 anymore, then I guess I would have expected that the installer should have refused to do the upgrade.  As it is, I'm screwed because the installer moved me from a version that worked to a version that was known to not run on the OS, with no (apparent) way to get back to where I was two days ago.

Cheers,

Dave

But recent versions of pgAdmin *have* been running on Windows 7.  Over the years I've religiously updated throughout v4, v5 and v6 (up until v6.2) and it's been running perfectly fine up until I upgraded from v6.2 -> 6.4 yesterday.

And I've tried reinstalling v6.2, but I'm now getting the same error.  So clearly it's just a configuration issue or compatibility issue with some other component (e.g., python 3.8) because it was able to run yesterday.

But looking back through my email history, I see I did have a problem updating to v5.0, that Dave Page kindly resolved.  I don't know if what I'm now experiencing is the same issue, but is there a similar work around, given that v6.2 was working perfectly fine yesterday?   I'd be happy to freeze at v6.2, if that's really the last version, but please don't make me go back to v4.30!

Yes - we stopped officially supporting Windows 7 with 4.30, but later rolled back the Python version so it would continue to work regardless. We recently had a round of updating the Python versions across the board, and I'll be honest, I completely forgot about the Windows 7 compatibility when we did that. Unfortunately though we really can't stick to an old version any longer; the longer we do so, the harder it becomes to update it later.

So I'm afraid if you're using Windows 7, you'll need to freeze at v6.2.

But... pgAdmin v4.30 runs fine.

So I believe the issue is that Python 3.9 has dropped support for Windows 7 and earlier, something which I for one didn't realise until I started looking into this (see https://www.python.org/downloads/windows/).

I've kicked off a build using Python 3.8 for testing. That claims to support back to Vista. I'll send a link once it's done.

Here's the Python 3.8 based test build. Note that I haven't tested it at all - I just kicked off the normal build process but told it to use 3.8 instead of 3.9.

https://developer.pgadmin.org/builds/2021-02-25python38-1/pgadmin4-5.0-x64.exe

Please let us know if it works on Windows 7.

Dave told me offlist that it's working for him.

So, we need to think about how long we'll support Windows 7. Sooner or later we will have to update Python... :-(

Cheers,

Dave

You said you were running 6.2 successfully and then upgraded right? I ask because I don't recall exactly when the buildfarm was updated, but if you were running 6.2, then it must have been built with 3.8 so uninstalling 6.4 and then installing 6.2 should put you back as you were.

 

Is there any way I can get a one-off 3.8 build... and then I'll never bother you again ;-) ?  Or is there some other post install fix?

The build systems for the release builds are fully automated, both in operation and deployment. I'm afraid manually rolling part of it back for a one-off build gives too much risk of messing things up.

It's possible one of the dev team has a test environment kicking around that they can run a build on. I do not, I'm afraid.

 

And as an aside, shouldn't the installer check for OS compatibility?  E.g., if you can't support Windows 7 anymore, then I guess I would have expected that the installer should have refused to do the upgrade.  As it is, I'm screwed because the installer moved me from a version that worked to a version that was known to not run on the OS, with no (apparent) way to get back to where I was two days ago.

It definitely should be possible to roll back to an older version, though that may require an uninstall/reinstall. The only thing that might get upset is the config database if the format has changed; we try to keep that backwards compatible, but it's not something we test regularly. Worst case with that should be simply moving the old one out of the way and restarting pgAdmin so it creates a fresh one.

And yes, the installer should do that, you're correct. I've blind-pushed a change that should do it - hopefully it won't break the build!

 

Cheers,

Dave
