I have managed to install Vufind2 in Debian Wheezy, with Koha 3.12.01. Under Auto Configure, all the values have been fixed. i.e.
    Basic Configuration... OK
    Cache... OK
    Database... OK
    Dependencies... OK
    ILS... OK
    Solr... Failed Fix
    Security... OK

The biggest problem is Solr...Failed Fix. I tried to change to port number 8081 from 8080 to no avail. backtrace is as follows
Exception:
