And install it, I got the same error:

2. MySQL Server im Safe Mode ohne Passworteingabe und ohne Netzwerk starten

MySQL wird nun im Safe Mode ohne Passwortabfrage gestartet. Da nun ohne Passwort auf die Datenbank zugegriffen werden
kann wird zusätzlich mit –skip-networking der Netzwerkzugriff unterbunden (kein muss aber zu empfehlen).

Then running:

sudo mysqld_safe --skip-grant-tables

configuration options for --syslog to take effect.

And looking into /var/log/mysql/error.log:

The important thing was: /usr/sbin/mysqld: Can't create/write to file '/tmp/ibGu3YIt' (Errcode: 13) and yeah, I don't know why, but /tmp belonged not to the root group. After fixing this, I could work again.

Use preload

Intending to save overuse of any SSDs, probably a bit out of date by now though :

browser.cache.disk.enable false
browser.cache.memory.max_entry_size 51200

browser.pagethumbnails.capturing_disabled with a value of true prevents thumbnails from appearing on the New Tab page grid and from being saved in ~/.cache/mozilla/firefox/profile_name/thumbnails.

This setting doesn't exist by default and is to be created.

Checking the file with file gave me the following output:

There is the tool icconf tool:
