[SOLVED] Read-only file system. Everything doesn't work.

[MattScherbatsky]

$this->bbcode_second_pass_code('', '[root@raspberrypi matt]# pacman -Syu
:: Synchronizing package databases...
error: failed to update core (unable to lock database)
error: failed to update extra (unable to lock database)
error: failed to update community (unable to lock database)
error: failed to update alarm (unable to lock database)
error: failed to update aur (unable to lock database)
error: failed to synchronize any databases
error: failed to init transaction (unable to lock database)
error: could not lock database: File exists
if you're sure a package manager is not already
running, you can remove /var/lib/pacman/db.lck
[root@raspberrypi matt]# rm /var/lib/pacman/db.lck
rm: cannot remove ‘/var/lib/pacman/db.lck’: Read-only file system')

$this->bbcode_second_pass_code('', '[matt@raspberrypi ~]$ ping www.google.it
-bash: /usr/bin/ping: cannot execute binary file')

Can you help me?
