Upgrade failed - Could not remove the psw5.3-fpm

Just try to update to 1.3.6 and it failed

I just followed the instructions for the debian upgrade
#### 3. Download and untar the distribution files

# cd /usr/local/src
# wget https://github.com/i-MSCP/imscp/archive/1.3.6.tar.gz
# tar -xzf 1.3.6.tar.gz

#### 4. Change to the newly created directory

# cd imscp-1.3.6

#### 5. Update i-MSCP by running its installer

# perl imscp-autoinstall -d

then this error came up

Error while performing step:
Processing Modules: : Plugin (tochange) task for: PhpSwitcher (ID 4)
