As I do this quite a bit during the setup procedures in our migration, I found
that this usually seems to result from a job that did not yet finish when the
instance is removed or that is just running interactively and I forgot about
it. `koha-shell`, `koha-mysql` in some other tmux-window come to mind.
(Usually, during removal I also get some complaint further down the stream as
well.)
Anyway, what you have left is a _Unix_ user named like your instance. So,
`deluser` (on Debian) is your friend to get rid of the user once all jobs of
said user are finished/closed.
Btw: The following function is from the j2k-setup script. Feel free to
cannibalize what you need to avoid this issue in the future.
```bash
koharemove() {
echo "************************************************************"
echo "* Start R E M O V E *"
echo "************************************************************"
# The following needs root rights!
# Remove a koha-instance from the system
# Mind that we need to stop all processes running by the instances
# user _first_ or we end up in some messy state
j2kshowconfig
for (( i=5; i > 0; i-- )); do
echo -n " $i "
sleep 1
done
echo -n " [ GO ] "
echo ""
echo "Disabling sites and shutting down ..."
sudo service apache2 stop
echo "Killing common interactive shells ..."
sudo killall -9 koha-mysql
sudo killall -9 koha-shell
echo "Stopping koha services ..."
sudo koha-zebra --stop $kohalibname
sudo koha-indexer --stop $kohalibname
sudo koha-worker --stop $kohalibname
echo -n "Waiting for background jobs to settle down"
for (( i=10; i > 0; i-- )); do
echo -n " $i "
sleep 1
done
echo ""
sudo service memcached stop
sudo a2dissite $kohalibname
echo "Removing $kohalibname ..."
sudo koha-remove $kohalibname
echo "Removing j2k created files and dirs ..."
sudo rm /usr/share/keyrings/koha-keyring.gpg
sudo rm /etc/apt/sources.list.d/koha.list
sudo rm -rf $j2kbin
sudo rm -rf $j2ketc
sudo rm -rf $j2kopac
sudo rm -rf $kohaopac/htdocs/j2ktheme
# echo '(Re)starting servers with default settings ...'
sudo service memcached start
sudo service apache2 start
}
```
