# Synchrotron
Synchrotron syncs package from Debian into the appropriate suites. E.g. Debian `testing` is synced to `landing`. This syncs source and binary packages. If a package in PureOS had downstream modifications (indicated by a `pureos` in the version number) it is excluded from the sync. Also packages than vanish from Debian are removed if possible.
# Remove a package
This is useful if one wants to remove a downstream forked package for example;
```
sudo -u dak
synchrotron sync unstable landing main <package name> --force
```
This command would force a sync between PureOS landing's "main" suite with Debian unstable.
