hi @lucasvm,
As I understood - did you run the composer install command before it? If yes - please add to the end of your command -vvv flag and give us output

Yes of course i have ran the composer install, there is no more web setup wizard install?, only cli?, im running php 7.3 on Ubuntu, do i need to install some php extension? the docs are not clear.

[ihor-sviziev]

Yes, in magento 2.4 there no more web installer. In case if you’ll have
some missing extension - composer install should fail. Could you rerun the
install command with -vvv flag at the end?

in case you download package from magento homepage you don't need run composer install. If you add extra package to composer.json just run composer update

From 2.4.0 magento install via cli only cause web wizard has removed
Cli command should add elasticsearch to avoid issue during cli run
--search-engine=elasticsearch7 --elasticsearch-host=elasticsearch --elasticsearch-port=9200 --elasticsearch-index-prefix=magento2 --elasticsearch-enable-auth=0 --elasticsearch-timeout=15
replace elasticsearch-host with your value correspoding your setting

[lucasvm]

I have installed via Composer, doing the create project.

Hello @lucasvm
cc: @ihor-sviziev

Not sure exactly but seems this issue related to your dev environment. Probably some required extension is missed or some artifacts in DB or code.

I verified this issue by the next steps:

1. Get Magento using composer as described here: https://devdocs.magento.com/guides/v2.4/install-gde/composer.html#get-the-metapackage

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition

1. Create empty DB and user for Magento.
2. Check that Elasticsearch is run and configured. More details here: https://devdocs.magento.com/guides/v2.4/config-guide/elasticsearch/es-overview.html
3. Install Magento using CLI. Example of my CLI

php bin/magento setup:install \
--db-host=db \
--db-name=magento_i3 \
--db-user=magento \
--db-password=123123q \
--base-url=http://magento.i3.loc \
--backend-frontname=admin \
--admin-user=admin \
--admin-password=123123q \
[email protected] \
--admin-firstname=Magento \
--admin-lastname=User \
--language=en_US \
--currency=USD \
--timezone=America/Chicago \
--skip-db-validation \
--elasticsearch-host=000.00.00.000 \
--elasticsearch-port=9200 \
--elasticsearch-index-prefix=instance_3 \
&& chown -R www-data:www-data .

Result:

• Magento 2.4.0 successfully installed.
• No errors like Class Magento\Framework\DB\Adapter\Pdo\Mysql\Interceptor does not exist during installation and after in log files

Please, review my steps and additional docs probably it has the answer.
Also, if I missed some details please let me know. Unfortunately without additional details, this issue could be closed as cannot reproduce

[lucasvm]

Ok thank you!, i think i have installed the software, i can see all the tables in the database, also the env file has been created, but when doing the setup upgrade im getting:
Could not validate a connection to Elasticsearch. No alive nodes found in your cluster

I dont have elasticsearch, its mandatory?

[mrtuvn]

@lucasvm yes 2.4 required elastic when install. Before you run cli for install make sure elastic service run

[ihor-sviziev]

Hi @lucasvm,
I’m closing this issue as it reproducing only when you don’t have configured elasticsearch, which is requirement for magento correct work.
