Plugin cannot be loaded since version 2.*

[pachico]

I have tried to load the plugin for both 2.0.1 and 2.0.2 versions but Grafana wont be able to load them.
Error simply says:

t=2020-07-20T11:46:08+0200 lvl=eror msg="Could not find plugin definition for data source: vertamedia-clickhouse-datasource"

We had to roll back to 1.9.5.

Can you have a look?
Thanks in advance

@pachico
could you describe your setup environment?
which grafana version do you use?
how you install vertamedia-clickhouse-datasource?

where is your plugin directory (by default /var/lib/grafana/plugins)?

could you share results of the following command?

grep -i -r plugin /etc/grafana

@Slach
grafana 7.1.0
OS: ubuntu 16.04
vertamedia-clickhouse-datasource errors with 2.0.1 and 2.0.2. Version 1.9.5 works smoothly
Plugins installed using cli, grafana-cli plugin install vertamedia-clickhouse-datasource, after install we restart the service

Output for 'grep -i -r plugin /etc/grafana'

/etc/grafana/grafana.ini:# Directory where grafana will automatically scan and look for plugins
/etc/grafana/grafana.ini:plugins = /var/lib/grafana/plugins
/etc/grafana/grafana.ini:# for new vesions (grafana itself and plugins), check is used
/etc/grafana/grafana.ini:# in some UI views to notify that grafana or plugin update exists

/etc/grafana/grafana.ini:# Enter a comma-separated list of plugin identifiers to identify plugins that are allowed to be loaded even if they lack a valid signature.

Could it be that version 2.0.* need to be specifically allowed?

@vblazquez please look https://github.com/Vertamedia/clickhouse-grafana#quick-start
add

[plugins]
allow_loading_unsigned_plugins=vertamedia-clickhouse-datasource

to grafana.ini

and run something like this

systemctl stop grafana-server
grafana-cli plugins install vertamedia-clickhouse-datasource 2.0.2
systemctl start grafana-server

    systemctl stop grafana-server
    grafana-cli plugins update vertamedia-clickhouse-datasource

    grafana-cli plugins ls

with

2.0.2 works fine with Grafana 7.1.0
