Failed to connect to the database #5958

This is caused by a missing PHP module, likely pdo_mysql. As this is not a bug in our software but an issue in your infrastructure please open this as https://help.nextcloud.com/ instead. |

@FrankMaute You can try php5 , it worked for me. |
|
I would ask to re-open this ticket. So I copied the files from the official nextcloud download page into the old folder - set the permissions for www-data and saw that it at least needs php7.1 which wasn't there with stretch yet so I updated to buster (not yet debian stable) with php7.3. For obvious reasons I cannot use PHP5.6 as suggested here, as NC16 requieres at least PHP7.1 Debian Buster |

Thank you @kesselb for the response - I have checked all my modules - my error was that I thought that the bug reporter with "php -i | grep "pdo"" would have already checked that module - in fact quite a lot of modules were missing on my installation (compared to https://docs.nextcloud.com/server/16/admin_manual/installation/source_installation.html) Would it be possible to maybe have a more explainatory error message in this case instead of an exception with stacktrace? Thanks |

apt install php7.4-mysql ... did solve this issue for me after upgrading ubuntu from 18.04 to 20.04 |
|
My case: success |
|
That's weird, my cron jobs started failing 5 days ago (same error message), thanks to this thread I figured out I had to reinstall php7.4-mysql as well as all these modules to fix it: Anybody has any cue as why it suddenly stopped working? |

Hey I seem to be having a simelar issue but the proposed solutions do not seem to fix anything. I do not have that much experience with Nextcloud and have no idea what this means. The error comes up when I try to autocomplete a command or run it. Both look like the same error! I hope somebody is able to help me with this!
