Resolved: Installing application in Plesk from CLI hangs at 0%

While attempting to install or update an application like WordPress via the Tools and Settings or from Domains, sometimes our customers find themselves facing a progress bar that does seem to be stuck on 0%.

In fact, sometimes the process does not finish even while trying to attempt the install or update via command line interface.

Installing application in Plesk from CLI hangs at 0%
# plesk bin aps -d -package-name mediawiki
The task to download APS package started. Task id: 77

Fortunately, our Support Techs have been able to get to the root of the issue. It seems the reason behind this issue is stuck tasks in the psa.longtasks table. We can view the stuck tasks by checking the longtasks table in the database:

# plesk db "select * from longtasks where status <> 'done'"
| 76 | aps-download | started | 0 | NULL | queue | NULL | 100 | 0 | 0000-00-00 00:00:00 | 0 | NULL |
| 77 | aps-download | started | 0 | NULL | queue | NULL | 100 | 0 | 0000-00-00 00:00:00 | 0 | NULL |

Our Support Techs recommend the following process to resolve the issue:

  1. First, connect to the server via RDP or SSH.
  2. Next, back up the psa database with the following command:
    # plesk db dump  > /path/to/.sql
  3. Then, delete stuck long tasks with the following command:
    # plesk db "delete from longtasks where status <> 'done'
  4. Finally, restore the database from the database dump with this command:
    # plesk db < /path/to/.sql
However, if you are still having trouble, our proficient Support Team would be happy to help you out.
