Packaging Troubleshooting

This page lists common problems and work-arounds.

This page needs expansion! If you encounter a new problem and solve it, feel free to add it here. If you encounter a problem you don't know how to solve, try asking on Stack Overflow, and be sure to add the "sandstorm.io" tag to your question. Or, talk to us on IRC (#sandstorm on freenode) or sandstorm-dev.

Note that language-specific issues should be documented in the language-specific guide pages, namely:

• Python
• Ruby on Rails
• Pure client apps

KeyError: 'getpwuid(): uid not found: 1000'

This is a Python bug. See the Python packaging guide for a work-around.

EROFS or "Read-only filesystem"

Only the /var directory is writable; the rest of the filesystem (which contains the contents of your app package) is read-only.

If your app wants to write to locations other than /var, and it's not easy to change the app's code, one work-around is to create a symlink from the location you app wants to modify to a location under /var. This won't work for all applications however.
