Disable all caches, especially Memcached?

 

[CedricV]

Missing install data caused this.

Try again with 2.3.2

Upgraded to 2.3.2, same error.

Disable the addons you have on your site and then try again

Just upgraded to 2.3.3... got the same error again.

Everything works fine, and the upgrade is complete... but this error always shows up at the end of an upgrade.

Try this.

It seems the error just shows up on this page: install/index.php?upgrade/run-job

If I just go to that page, the error shows up... even if there is no running job.

Does your cache config in config.php use list format, something like:

$config['cache']['config'] = [
'servers' => [
['/var/run/memcached/memcached.sock', 0]
]
];

i.e. servers rather than server, and a list of one or more servers, with a number after the socket/hostname? I had similar issues and they went away when I simplified the config to
$config['cache']['config'] = [
'server' => '/var/run/memcached/memcached.sock'
];
