Unable to install an application: the installation hangs

Applicable to:

  • Plesk for Linux

Symptoms

  • Unable to install an application: the installation hangs.
  • In the panel.log the following messages are written:

    [timestamp] DEBUG [util_exec] [585450128201e] Starting: filwrpr /usr/local/psa/admin/bin/filwrpr '87'
    [timestamp] DEBUG [util_exec] [585450128201e] Finished in 0.11996s, Result: TRUE
    [timestamp] DEBUG [util_exec] [58545012b22f0] Starting: filwrpr /usr/local/psa/admin/bin/filwrpr '11'
    [timestamp] DEBUG [util_exec] [58545012b22f0] Finished in 0.07481s, Result: TRUE

Cause

The file /usr/local/psa/admin/plib/scripts/task-async-executor.php is corrupted.

Resolution

File /usr/local/psa/admin/plib/scripts/task-async-executor.php is a part of plesk-core package. Corrupted file can be replaced as follows, e.g. for Plesk 12.5 for CentOS 7:

1. Download and extract appropriate plesk-core package from autoinstall.plesk.com :


# mkdir /root/plesk-core && cd /root/plesk-core

# wget http://autoinstall.plesk.com/PSA_12.5.30/dist-rpm-CentOS-7-x86_64/base/plesk-core-12.5.30-cos7.build1205150826.19.x86_64.rpm
# rpm2cpio plesk-core-12.5.30-cos7.build1205150826.19.x86_64.rpm | cpio -idmv

2. Create backup of original file and replaced it with the extracted one:


# cp /usr/local/psa/admin/plib/scripts/task-async-executor.php{,.original}

# cp /root/plesk-core/usr/local/psa/admin/plib/scripts/task-async-executor.php /usr/local/psa/admin/plib/scripts/task-async-executor.php

3. Install an application again
