Hitting the exact same Problem here, _KUL.

Since the question did not raise a lot of attention here I wanted to share my workaround.

You can get this thing going by just replacing the function call of the “state_machine” which is made from within in the “wizard” function defined in
/usr/share/openproject/installer/wizard line 60

with the function definition of “state_machine” as defined in
/usr/share/openproject/installer/addons/legacy-installer/bin/configure line 113

That is replace line 60 here
/usr/share/openproject/installer/wizard:

54 wizard() {
 55         STATE="$1"
 56         while true; do
 57                 wiz_debug "STATE=$STATE OLDSTATE=$OLDSTATE"
 58                 OLDSTATE="$STATE"
 59                 _wiz_reset "$STATE"
 60                 state_machine "$STATE"
 61                 if [ "$OLDSTATE" = "$STATE" ]; then
 62                         STATE="same-state" 
 63                 fi
 64         done
 65 }       

with line 113 and following from here
/usr/share/openproject/installer/addons/legacy-installer/bin/configure

113 state_machine() {
114         case "$1" in
115                 "start")
116                         input_start 
117                         ;;
118                 "done")
119                         break
120                         ;;
121                 *)
122                         echo "invalid state: ${STATE}"
123                         break;
124                         ;;
125         esac 
126 }               

You should end up with a wizard function ( in /usr/share/openproject/installer/wizard ) that looks like this:

54 wizard() {
 55         STATE="$1"
 56 #       while true; do
 57 #               wiz_debug "STATE=$STATE OLDSTATE=$OLDSTATE"
 58 #               OLDSTATE="$STATE"
 59 #               _wiz_reset "$STATE"
 60 #               state_machine "$STATE"
 61 #               if [ "$OLDSTATE" = "$STATE" ]; then
 62 #                       STATE="same-state"
 63 #               fi
 64 #       done
 65         while true; do
 66         wiz_debug "STATE=$STATE OLDSTATE=$OLDSTATE"
 67                 OLDSTATE="$STATE"
 68         _wiz_reset "$STATE"
 69         case "$STATE" in
 70                 "start")
 71                         input_start
 72                         ;;
 73                 "done")
 74                         break
 75                         ;;
 76                 *)
 77                         echo "invalid state: ${STATE}"
 78                         break;
 79                         ;;
 80         esac
 81  
 82                 if [ "$OLDSTATE" = "$STATE" ]; then
 83                         STATE="same-state"
 84                 fi      
 85         done    
 86 
 87 }

54 wizard() {

55 STATE=“$1”
56 # while true; do
57 # wiz_debug “STATE=$STATE OLDSTATE=$OLDSTATE”
58 # OLDSTATE=“$STATE”
59 # _wiz_reset “$STATE”
60 # state_machine “$STATE”
61 # if [ “$OLDSTATE” = “$STATE” ]; then
62 # STATE=“same-state”
63 # fi
64 # done
65 while true; do
66 wiz_debug “STATE=$STATE OLDSTATE=$OLDSTATE”
67 OLDSTATE=“$STATE”
68 _wiz_reset “$STATE”
69 case “$STATE” in
70 “start”)
71 input_start
72 ;;
73 “done”)
74 break
75 ;;
76 *)
77 echo “invalid state: ${STATE}”
78 break;
79 ;;
80 esac
81
82 if [ “$OLDSTATE” = “$STATE” ]; then
83 STATE=“same-state”
84 fi
85 done
86
87 }

I am not much of a bash buy, so I don’t really understand why this resolves the issue or what the problem was in the first place. It looked perfectly fine to my eyes; My best guess is “something to do with variable scopes…”.
Maybe someone more versed in these things sheds some light onto this in the future.

For the moment however this does get the installer to work which is good enough for me
