This is not related to your problem, but the change implies that your system has changed how Apache accesses PHP (from Apache's mod_php to using the php fast-cgi process manager). Worth noting in case of future issue - Andrew.

I could finally fix it,
apt install --reinstall php-gd php-intl php-json php-mbstring php-mysqli php-phar php-cgi php-cli php-bz2 php-zip php-pclzip
After that, when checking Internal PHP settings relevant to CQPweb in the Admin Control Panel, I realised that php.ini file is no longer apache2/php.ini but /etc/php/8.1/fpm/php.ini. Then, I applied settings for upload_max_filesize post_max_size memory_limit max_execution_time and mysqli.allow_local_infile. Then restarted apache and all wen almost as expected, except that I get this error now:

Some bug reports on the web suggest that adding
loose-local-infile=1
in the [client] section of your mysql configuration may help?
Other possibilities:
* Check that cqpusr has the "FILE" privilege on the sql server.
* Check that the input file is readable by system user www-data.
* Check that no other system (like apparmor) is causing problems by limiting what folders the webserver / mysql client can access.

Sorry Andrew for keeping going on with this, but I find no solution...
I turn back to false $mysql_has_file_access
and, as it says in the manual:
default value of secure file priv has changed. In this case, instead of changing the value of
secure file priv, to fix the problem you need to add a line secure file priv="" to your
my.cnf file to restore what was previously the default state.
It's unknown whether this issue affects MariaDB as well as MySQL.
first, I have tried adding
secure_file_priv = ""
to /etc/mysql/mysql.conf.d/mysqld.cnf
mysql> show variables like "secure_file_priv";
+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| secure_file_priv | |
+------------------+-------+
1 row in set (0,01 sec)
results in:
Got error 'PHP message: PHP Fatal error: Uncaught mysqli_sql_exception: LOAD DATA LOCAL INFILE is forbidden
second, I have tried adding:
secure_file_priv = /corpora/cqp/tmp/
mysql> show variables like "secure_file_priv";
+------------------+---------------------------+
| Variable_name | Value |
+------------------+---------------------------+
| secure_file_priv | /corpora/cqp/tmp/ |
+------------------+--------------------------+
1 row in set (0,01 sec)
where
ls -la /corpora/cqp/
drwxrwxr-x 2 www-data cqpweb 217088 sep 19 17:46 tmp
and
grep '^cqpweb:.*$' /etc/group | cut -d: -f4
mysql,www-data
but the same error comes up
Got error 'PHP message: PHP Fatal error: Uncaught mysqli_sql_exception: LOAD DATA LOCAL INFILE is forbidden

I've searched for secure_file_priv in /etc/mysql/mysql.conf.d/mysqld.cnf and there is no instance of it, just in case I also searched in /etc/php/8.1/apache2/php.ini and nothing too...
I've changed from false to
$mysql_has_file_access = true;
in /lib/defaults.inc.php and /lib/defaults.php:
and now the error has changed to something more weird:

I looked for the database configuration in lib/config.inc.php
and could enter mysql with the data stored there, I mean the mysqluser and the mysqlpassword for the cqpwebdb. Just in case I granted again the database to the same user, but I still get that same last error.

That clarifies what the problem is. It's not in PHP. It's in MySQL. Even though local infile is switched on, something else is blocking it.
I hesitate to ask, but you did check the setting of secure_file_priv, right? It's listed in the manual as one of the things to check if infile doesn't work.
Section "Known "gotchas" in SQL DB setup"; paragraph "File privilege with restricted scope"
(you could also try just setting $mysql_has_file_access in cqpweb, so that LOCAL isn't needed)

There's no alternative to you breaking out the mysql client and having a poke around to work out what is causing the problem.
EG to find out whether the mysqld configuration is taking effect, you need to run
> show variables like "local_infile";
In order to get
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile | ON |
+---------------+-------+
If it's ON, that suggests the issue is in PHP (or, some other security setting). If it's OFF, the issue is that your mysql config file is not taking effect.
Also, running the load data command , ie
LOAD DATA LOCAL INFILE '/mnt/vmdata/corptedig-glif/corpora/cqp/tmp/___install_temp_metadata_bnc' INTO TABLE `text_metadata_for_bnc` FIELDS ESCAPED BY ''
manually in the client might result in a more informative error message (also might not, mysql err messages are not noted for their helpfulness)

In /etc/mysql/mysql.conf.d/mysqld.cnf i tried
local_infile = true
local_infile = 1
local_infile = On
but no improvement
The error is not shown in the web interface when $print_debug_messages = true; but in the apache error log
Last thing showing in the web interface with debug activated is:

The other possibility is "local_infile = true" as the culprit. I am not sure the mysql ini file parser recognises "true". You might try "On" or "1" instead.
If that fails, you'll have to move to digging with mysql client to see what the server settings actually are in practice and where they are being set.

Thanks Andrew for your answer, but I'm sorry to say, that when I detected the problem i had
;mysqli.local_infile_directory =
then, as suggested by the error log, I activate it, but nothing changed, I have commented out already...

My guess: You've caused it by setting local-infile-directory.
That's a string setting, which if set limits LOCAL INFILE to a particular directory. You've set it to Boolean true, which translates to string "1". Obviously this will block infile from working anywhere.
