NO_PUBKEY-Fehler beseitigt

Problem

Bei
sudo apt-get update
kam am Ende immer:
Paketlisten werden gelesen... Fertig
W: GPG-Fehler: http://ppa.launchpad.net trusty Release: Die folgenden Signaturen konnten nicht überprüft werden, weil ihr öffentlicher Schlüssel nicht verfügbar ist: NO_PUBKEY D8D05E222E10C9E3

(Linux Mint 17.3 Rosa KDE)

Lösung:
Schlüssel explizit importieren, wie in: http://forum.linux-mint-czech.cz/viewtopic.php?t=1767&p=11119

Mysql-Datenbank von Akonadi repariert

Problem
Nach Umzug von openSuse 13.2 auf Mint 17.3 (KDE 4.14.2) funktionierte KMail (4.14.2) nicht mehr.
Akonadi startete zwar, aber kmail meldete gleich beim Starten einen Fehler („Fehler beim .. der Ressourcen-Collection“ oder so).
Über die Akonadiserver-Konfiguratioon in der akonadiconsole (Button „Test“) die Fehlermeldungen angeschaut, in einer der Dateien stand:
„MySQL server has gone away“
Denn der Mysql-Server stoppte gleich nach dem Start, mit folgendem mysql.err:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

key_buffer_size=16384
read_buffer_size=131072
max_used_connections=48
max_threads=256
thread_count=48
connection_count=48
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 560024 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Lösung

# Wiederherstellen der Original-Datenbank
mv .local/share/akonadi/ .local/share/akonadi_160109c_kop2
cp -a ../sunito_zuse132/.local/share/akonadi/ .local/share/akonadi/

# in der mysql.conf den Eintrag innodb_force_recovery auf 2 gesetzt (1 funktionierte nicht)
kwriteconfig --file /home/sunito/.local/share/akonadi/mysql.conf --group mysqld --key innodb_force_recovery 2

# Mysql alleine (ohne Akonadi) gestartet:
akonadictl stop
killall /usr/sbin/mysqld
mkdir /tmp/akonadi-sunito.vZoEHB/
/usr/sbin/mysqld --defaults-file=/home/sunito/.local/share/akonadi/mysql.conf --datadir=/home/sunito/.local/share/akonadi/db_data/ --socket=/tmp/akonadi-sunito.vZoEHB/mysql.socket

# Den Server in seinem Konsolefenster laufen lassen, in neuem Fenster die ganze Datenbank gedumpt:
mkdir /opt/ms/dump1/
mysqldump -S /tmp/akonadi-sunito.vZoEHB/mysql.socket -A >/opt/ms/dump1/a2all.sql # 2016-01-09 17:23:24
# Danach den Mysql-Server weieder beendet:
killall /usr/sbin/mysqld

# Dann die Datenbank-Daten weggemovet:
mv .local/share/akonadi/db_data/ .local/share/akonadi/db_data_zuse-kaputt
mv .local/share/akonadi/file_db_data/ .local/share/akonadi/file_db_data_zuse-kaputt
# und den DB-Ordner wieder erstellt:
mkdir .local/share/akonadi/db_data
# in der mysql.conf den Eintrag innodb_force_recovery wieder entfernt
kwriteconfig --file /home/sunito/.local/share/akonadi/mysql.conf --group mysqld --key innodb_force_recovery 0

# Nun in dem vorigen Fenster wieder Mysql gestartet:
/usr/sbin/mysqld --defaults-file=/home/sunito/.local/share/akonadi/mysql.conf --datadir=/home/sunito/.local/share/akonadi/db_data/ --socket=/tmp/akonadi-sunito.vZoEHB/mysql.socket
# Dann die DB aus dem Dump wiederhergestellt:
mysql -S /tmp/akonadi-sunito.vZoEHB/mysql.socket # Und Mysql-Server weieder beendet:
killall /usr/sbin/mysqld

# Nun Akonadi gestartet
akonadictl start

–> Läuft!!!

 


 

Dann festgestellt, dass einige Konfigurationsdateien nicht im neuen Userverzeichnis angekommen waren:

cp -a ../sunito_zuse132/.kde4/share/config/akonadi_pop3_resource_[1-9]*rc ~/.kde/share/config

Allerdings stimmen dan die in diesen Dateien eingetragenen Zielordner-IDs (targetCollection) nicht mehr. Mühsam manuell per GUI geändert (ohne Internetverbindung, damit keine Mails in die falschen Odner gelangen).
