Occasionally Amahi applications fail to install properly. This is often noted by error messages in the application install log (/var/log/amahi-app-install.log).

Other times, you may receive notice in the Dashboard.

We take these seriously and have tried to incorporate additional error checking/prevention methods. Unfortunately they don't catch everything.

Reasons for failure vary, but the most common are:

• Slow or sporadic internet connection.
• Install script:
  • Taking too long
  • Incorrect syntax
  • Insufficient privileges
• Application source file is unavailable.
  • New version
  • File moved
  • Wrong SHA1 hash

There are some recommendation users can follow to help correct or prevent these problems.

DON'T:

1. Refresh your web browser or navigate from the page while an application is installing.
2. Try to install an application after it initially fails. Need to diagnose issue.

DO:

1. Check the log for details of why the app install failed.
2. Check the Dashboard Apps tab, Installed section for the app.
3. Check /var/hda/web-apps to ensure the app did not partially install.
4. File a bug report.
