That may be the first time you authenticated sudo in that terminal, so you need to put in your Ubuntu user password first and once that is successful, it will ask you for your sql user / password. | A: Look carefully, even though you typed mysql -u.... you have a sudo preceding it.

- | A: Usually the culprit is sudo if you are new to Ubuntu. You usually see sudo this and sudo that, and then you launch an application with sudo, like gedit or kate or whatever. Sudo means you are now pretending to be root. The files you save don’t know that, and will say they belong to root. Don’t use sudo unless 100% needed. You will have to use chown on each and every file you saved as root. Don’t do this willy-nilly as there are files supposed to be owned by root, only the files belonging to you. | + | A: Usually the culprit is sudo if you are new to Ubuntu.

Je l’ai installé moi-même à partir de linuxgenie.net et tout s’est bien passé. Je me suis couché et le lendemain je n’arrivais plus à me connecter. Le mot de passe ne peut pas être mauvais, car j’ai choisi « zxcvb » parce que c’est dans une VM sans réseau et je l’ai utilisé toute la nuit. Voici ce qu’affiche le terminal : sudo mysql -u root -p [sudo] password for Sydney: Sorry, try again [sudo] password for Sydney: Sorry, try again.

+ | |||
+ | R : Le coupable est généralement sudo si vous débutez sous Ubuntu. Vous avez l’habitude de voir sudo ceci et sudo cela, puis vous lancez une application avec sudo, comme gedit ou kate ou n’importe quoi. Sudo signifie que vous prétendez être root. Les fichiers que vous avez sauvegardés ne le savent pas et diront qu’ils appartiennent à root. Il ne faut pas utiliser sudo à moins d’en avoir besoin à 100 %. Vous devrez utiliser chown sur chacun des fichiers que vous avez enregistrés en tant que root. Ne le faites pas n’importe comment, mais uniquement sur les fichiers qui vous appartiennent, | ||
