Hi,

I have initially installed with confd-8.0.14 and uninstalled then installed with confd-8.0. I am seeing the below error, any idea?

This issue is always seen on a clean cluster with all the fresh volume mounts, then install 8.0.14, uninstall and install 8.0 version of confd.

Hi. The simple answer is that the fxs for ailf-rollback.yang moved in 8.0.2:

8.0.14:

```auto
$ find . -name tailf-rollback.fxs
./lib/confd/lib/core/confd/priv/tailf-rollback.fxs

```

8.0:

```auto
$ find . -name tailf-rollback.fxs
./etc/confd/tailf-rollback.fxs

```

so ConfD needs the right load path for this fxs (and several other fxs’s). I was able to stop a running 8.0.14 and restart with 8.0 by setting my $CONFD\_DIR to the 8.0 installation but your installation might have some overlap or other dependencies that you might have given the change of location of this .fxs. But, hopefully this is enough info to allow you to get past this issue.
