Ok, das liegt daran, dass du "roave/security-advisories": "dev-master" als Requirement drin hast. Das war in früheren Versionen der Contao Managed Edition dabei, wurde aber später wieder entfernt. Jedenfalls könntest du das auch einfach entfernen.

Warum das aber dieses Problem verursacht, ist noch nicht klar.

[wdm]

Ich habe mir jetzt erstmal mit "meiner funktionierenden Lösung" (manuelles editieren der composer.lock) beholfen. Damit hat es funktioniert.
Da dies eine Liveinstallation ist, wollte ich die Seite nicht ewig vom Netz nehmen.

Ich kann das aber auch nochmal in einer anderen Installation versuchen. Dort ist auch das security-advisories Paket nicht installiert.

Ich habe das Problem mal mit Jordi auf Twitter diskutiert: https://twitter.com/fritz_mg/status/1012296407003344899
Es hilft dem resolver, wenn man bspw. das core-bundle auf ^4.4.20 setzt und das manager-bundle auf ~4.4.20.

[wdm]

Im Contao Manager oder in der composer.json?

Im Contao Manager finde ich diese beiden Pakete so explizit gar nicht.

[tab]

Würde es nicht auch helfen, die roave/security-advisories rauszunehmen? Wird ja wohl eh nicht mehr gebraucht/installiert in neueren Versionen von Contao

[wdm]

Daran scheint es nicht zu liegen. Ich habe die gleichen Probleme auch in jeder anderen Contao 4 Installation, wo dieses Paket nicht installiert ist.

Interessant, ich hatte bisher das Problem noch bei gar keiner Installation. Sowohl bei Update über die Cloud als auch direkt auf dem Webserver.
