Ich habe kürzlich eine Neuinstallation von Ubuntu 16.04 durchgeführt. Ich habe auch installiert mysql-server
und mysql-client
(deren Standardversion 5.7.12) über apt-get install
.
Da 5.7.12 einige Probleme aufwies, entschied ich mich, es zu deinstallieren. Ich habe es apt-get remove mysql-server mysql-client
zuerst versucht, aber gesehen, dass Artefakte gefallen /etc/mysql
und /var/lib/mysql
nicht entfernt wurden.
Ich habe es dann versucht apt-get --purge removed mysql-server mysql-client
, aber immer noch keinen Unterschied.
Also habe ich sie manuell entfernt (via rm -rf
). Ich entfernte auch manuell alle *mysql*
Dateien darunter /usr/
, die von irgendwelchen mysql-*
Abhängigkeitspaketen wie kamen mysql-common
.
Bei der Neuinstallation mysql-server and -client
stelle ich jedoch fest, dass dies nicht möglich ist.
Tatsächlich bin ich jetzt in einem Zustand, in dem ich weder apt-get remove mysql-server
noch kann apt-get install mysql-server
!
Wie kann ich die Situation beheben, in der ich mich befinde? Wie repariere ich meine lokalen Paket-Repository-Metadaten, wenn sie beschädigt sind?
Ich würde es hassen, das ganze gesegnete Betriebssystem mit all meinen anderen Apps und Umgebungen neu zu installieren, ein weiteres Mal nur wegen mysql-server
.
Der folgende Fehler wird beispielsweise angezeigt, wenn ich versuche, ihn zu entfernen mysql-server
:
$ apt-get remove mysql-server

die ich mit anderen Varianten von Installationsbefehlen bekomme.
sudo apt-get remove --purge mysql-server-5.7
. Beachten Sie, dass es sich hier wirklich mysql-server-5.7
um etwas handelt, nicht um etwas mysql-server
.
mysql-server-5.7
in einem schlechten Zustand ist, versuchen Sie es erneut zu installieren:sudo apt-get install --reinstall mysql-server-5.7
.
