## Troubleshooting
### ERROR: /etc/conf.d/snapper does not exist!
*snap-pac* reads in the snapper configurations from `/etc/conf.d/snapper`. It
can't do that if the file doesn't exist. I'm not sure what you've done to not
have it exist in the default location.
### WARNING: No snapper configurations found, so not taking any snapshots!
No snapper configurations were found in `/etc/conf.d/snapper`. This means you
haven't created any configurations yet using `snapper create-config`. See the
snapper manpage on how to do this.
### WARNING: No snapper configurations are set up for snapshots to be taken!
Although you seem to have created at least one configuration, none of them are
set up for *snap-pac*'s pacman hooks. By default *snap-pac* will take snapshots
for the `root` configuration and any other configuration which has
`PACMAN_PRE_POST` set to `yes` in its configuration file. This message means you
don't have a snapper configuration named `root` (or `PACMAN_PRE_POST` is set to
`no` for it) and no other configuration is set up for snapshots. See the
configuration section above.
### WARNING: *prefile* does not exist, so no post snapshot will be taken. If you are initially installing snap-pac, this is normal.
*snap-pac* saves the pre snapshot's number in a temporary file. Somehow it go
removed before the post snapshot could be taken. When you initially install
*snap-pac* the post hook is run, but the pre hook never was, so this message
will show up then as well.
