mu init -- initialize the mu message database
mu [common-options] init [options]
mu init is the subcommand for setting up the mu message database. After mu init has completed, you can run mu index
starts searching at <maildir>. By default, mu uses whatever the MAILDIR environment variable is set to; if it is not set, it tries ˜/Maildir if it already exists.
specifies that some e-mail addresses are ’my-address’ (the option can be used multiple times). Any message in which at least one of the contact fields contains such an address is considered a ’personal’ messages; this can then be used for filtering in mu-find(1), mu-cfind(1) and mu4e, e.g. to filter-out mailing list messages.
<my−email−address> can be either a plain e-mail address (such as [email protected]), or a basic PCRE regular-expression (see pcre(3) for details), wrapped in / (such as /foo−.*@example\.com/). Depending on your shell, the argument may need to be quoted.
reinitialize the database from an earlier version; that is, create a new empty database witht the existing settings. This cannot be combined with the other init options.
This command returns 0 upon successful completion, or a non-zero exit code otherwise. Typical values are 2 (no matches found), 11 (database schema mismatch) and 12 (failed to acquire database lock).

You need to re-initialize mu, see mu-init(1)
Some other program has exclusive access to the mu (Xapian) database
use a non-default directory to store and read the database, write the logs, etc. By default, mu uses the XDG Base Directory Specification (e.g. on GNU/Linux this defaults to ˜/.cache/mu and ˜/.config/mu). Earlier versions of mu defaulted to ˜/.mu, which now requires −−muhome=˜/.mu.
The environment variable MUHOME can be used as an alternative to −−muhome. The latter has precedence.
