Not sure how / why that happens … it sounds like somehow mysql got suddently unreachable despite the system being able to initialize stuff as usual earlier during the install …
Are you able to reproduce that exact same issue if you try again ?
ampache has some known issue currently investigated - though unfortunately not displayed in the app catalog for now …
wekan’s install log indicate that it can only be installed on x86 64bit architecture (supposedly you’re on ARM)
Still puzzled by the failed error message for wordpress … Re-checking the log, I’m seeing there’s an error 504 earlier and pretty sure it’s not supposed to happen … but despite this wordpress seems to get configured correctly later … and it only crashes when enabling the plugin … But then I don’t have that much expertise on this app to know better
