I have a virtual machine that may have two conflicting Koha installations. What, if anything, can I do that will wipe all Koha installations completely, and install a new stable from scratch, following https://wiki.koha-community.org/wiki/Debian? I don't know if I *exactly* need to go so far as to delete details like the Koha repository in aptitude... but I am willing to do so if I am advised. I do think it would be better to wipe any Koha-created directory heirarchies, and drop any Koha-related databases. (Note: My system doesn't contain any valuable information *in* Koha; the only loss would be the time and energy to delete and rebuild the installation.) -- christos Jonathan Seth Hayward, An Orthodox Christian author.
