aptly mirror update

Updates remote mirror (downloads package files and meta information). When mirror is created, this command should be run for the first time to fetch mirror contents. This command could be run many times to get updated repository contents. If interrupted, command could be restarted safely.


$ aptly mirror update <name>

Params are:

  • name is a mirror name (given when mirror was created)

All packages would be stored under aptly’s root dir (see section on Configuration).


  • -force: force mirror update even if locked by another process
  • -download-limit=0: limit download speed (kbytes/sec)
  • -ignore-checksums: ignore checksum mismatches for downloaded items (package files, metadata)
  • -ignore-signatures: disable verification of Release file signatures
  • -keyring=trustedkeys.gpg gpg keyring to use when verifying Release file (could be specified multiple times)
  • -max-tries=1: Max download tries till process fails with download error
  • -skip-existing-packages: do not check file existence for packages listed in the internal database of the mirror 1.1.0

While updating mirror, aptly would verify signature of Release file using GnuPG. Please read information about signature verification in aptly mirror create command description.

Concurrent operations while mirror is updated

Mirror update is split in two phases:

  • initial download of Release and Packages files, parsing, analyzing
  • download of packages files

During second phase aptly would unlock the database and allow other aptly commands to be run while the mirror is being updated. Any operations with the mirror currently updated would result in error and aptly mirror show would show updating status. At the end of the mirror update operation, aptly would re-open the database and store final status of the mirror.

If mirror update status would be stored in wrong way in DB (e.g. after crash), mirror update lock could be overridden with flag -force.
