Component Install: DB function reports no errors - joomla

Question

When trying to install a component I am getting this error.
Component Install: DB function reports no errors
Error installing component

Answer 1

I am getting this error quite often on a test system when trying to install a component which uses SQL updates and causes first time when installing an error (even not SQL related, such a missing file from the manifest file).
Here are some steps on how to fix this, by manually uninstalling the component, as from the Extension manager the installation may / will fail.
Find the id of your extension (you may also find multiple entries)
SELECT *
FROM `#__extensions`
WHERE `name` LIKE '%myextensionname%'
LIMIT 0 , 30
Remove from #__schemas the entries for extension, where extension_id is the previous found id. Remove also any entries for non existing extensions:
Remove any assets for your extension:
SELECT *
FROM `#__assets`
WHERE `name` LIKE '%myextensionname%'
LIMIT 0 , 30
Remove any menu entries:
SELECT *
FROM #__menu
WHERE link LIKE '%myextensionname%'
LIMIT 0 , 30
Reinstall.

Answer 2

Not tested but this is the general idea I would use.

This an error / typo free version of what #Elin proposed (in case somebody wants to take this further). This solution did NOT work for me, but I think it has something in it.
