+# Final Blockscout Fix - Corrected Commands
+
+## Issues Found
+1. `Explorer.Release.migrate/0 is undefined` - Need to use `bin/blockscout migrate` instead
+2. docker-compose.yml syntax error - sed command created invalid YAML quotes
+
+## Corrected Commands (Run in VMID 5000)
+
+### Step 1: Run Migrations Using Correct Command
+
+```bash
+# Use 'migrate' command instead of 'eval'
+docker run --rm \
+  --network host \
+  -e DATABASE_URL=postgresql://blockscout:blockscout@localhost:5432/blockscout \
+  blockscout/blockscout:latest \
+  bin/blockscout migrate
+```
+
+### Step 2: Verify Tables
+
+```bash
+docker exec blockscout-postgres psql -U blockscout -d blockscout -c "
+SELECT 
+  CASE WHEN EXISTS (SELECT 1 FROM information_schema.tables WHERE table_name = 'migrations_status') 
+    THEN '✅ migrations_status' ELSE '❌ MISSING' END,
+  CASE WHEN EXISTS (SELECT 1 FROM information_schema.tables WHERE table_name = 'blocks') 
+    THEN '✅ blocks' ELSE '❌ MISSING' END,
+  CASE WHEN EXISTS (SELECT 1 FROM information_schema.tables WHERE table_name = 'transactions') 
+    THEN '✅ transactions' ELSE '❌ MISSING' END;
+"
+```
+
+### Step 3: Fix docker-compose.yml Properly
+
+```bash
+cd /opt/blockscout
+
+# Check current command
+grep -A 1 "command:" docker-compose.yml
+
+# Backup
+cp docker-compose.yml docker-compose.yml.backup
+
+# Method 1: Use Python to properly escape (if available)
+python3 << 'PYTHON'
+import re
+
+with open('docker-compose.yml', 'r') as f:
+    content = f.read()
+
+# Replace command line with properly escaped version
+pattern = r'command:\s*.*blockscout start'
+replacement = 'command: sh -c "bin/blockscout migrate && bin/blockscout start"'
+
+content = re.sub(pattern, replacement, content)
+
+with open('docker-compose.yml', 'w') as f:
+    f.write(content)
+
+print("✅ Updated docker-compose.yml")
+PYTHON
+
+# Method 2: Manual edit (if Python not available)
+# Edit docker-compose.yml manually and change:
+# command: /app/bin/blockscout start
+# To:
+# command: sh -c "bin/blockscout migrate && bin/blockscout start"
+```
+
+### Step 4: Alternative - Edit docker-compose.yml Manually
+
+If sed is causing issues, edit manually:
+
+```bash
+cd /opt/blockscout
+nano docker-compose.yml  # or vi docker-compose.yml
+
+# Find the line with:
+#   command: /app/bin/blockscout start
+# Or:
+#   command: bin/blockscout start
+
+# Replace with:
+#   command: sh -c "bin/blockscout migrate && bin/blockscout start"
+
+# Save and exit
+```
+
+### Step 5: Restart
+
+```bash
+cd /opt/blockscout
+docker-compose down blockscout
+docker-compose up -d blockscout
+
+# Wait and check
+sleep 30
+docker ps | grep blockscout
+docker logs blockscout 2>&1 | tail -20
+```
+
+## Complete One-Line Fix (Manual Edit Required)
+
+```bash
+# Run migrations
+docker run --rm --network host -e DATABASE_URL=postgresql://blockscout:blockscout@localhost:5432/blockscout blockscout/blockscout:latest bin/blockscout migrate && \
+cd /opt/blockscout && \
+# Then manually edit docker-compose.yml to add: command: sh -c "bin/blockscout migrate && bin/blockscout start" && \
+docker-compose restart blockscout
+```
