- Make sure you are not running multiple versions of Garden or Mutagen at the same time. - If you recently upgraded or downgraded Garden, ensure you have stopped all daemons and processes as above. - If you are on ARM or a non-x86 platform, there may be additional compatibility issues—ensure you are using the latest Garden version, as some fixes for ARM were released in recent versions. --- ### 5. Additional Debugging You can list active syncs to see if any are stuck:

sh
garden util mutagen sync list

[Reference: List active syncs]() If the error persists after these steps, consider sharing your debug logs with the Garden team or community for further assistance. --- Summary: This error is most often caused by stuck Mutagen processes or a sync daemon that needs to be restarted. Stopping all daemons, killing lingering processes, and redeploying usually resolves the issue. If not, check for version mismatches or platform-specific bugs, especially if you are on ARM or have recently upgraded Garden. Let me know if you need more specific help or if you see a different error after following these steps! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

---------------------- The error message

Could not flush synchronization changes, retrying

during

garden deploy --sync

typically points to an issue with the underlying Mutagen synchronization process. This can happen if there are lingering Mutagen processes, version mismatches, or problems with the sync daemon. Here are steps you can take to debug and resolve the issue, based on the official documentation and community troubleshooting: --- ### 1. Check for Lingering Mutagen Processes Lingering or stuck Mutagen processes can cause sync issues. Kill any running Mutagen processes:

sh
kill -9 $(pgrep mutagen)

[See troubleshooting advice]() --- ### 2. Stop the Sync Daemon Before restarting or redeploying, ensure all sync daemons are stopped. Run these commands from your project root:

sh
garden util mutagen daemon stop

If you are using a Garden version between 0.13.26 and 0.13.33 and have switched sync modes, you may need to use the

GARDEN_ENABLE_NEW_SYNC

environment variable as described in the docs:

sh
GARDEN_ENABLE_NEW_SYNC=false garden util mutagen daemon stop
GARDEN_ENABLE_NEW_SYNC=true garden util mutagen daemon stop

[Reference: Troubleshooting sync daemon]() --- ### 3. Redeploy with Sync After stopping all daemons and killing lingering processes, redeploy with sync enabled:

sh
garden deploy --sync

@microscopic-river-74022 Error: unable to flush session: session is not currently able to synchronize Here's the full output: Forcing synchronization cycle for session sync_8yO1KsKR1Q7SuINsDjBNuTvCAUt9Eyb6u Error: unable to flush session: session is not currently able to synchronize

---------------------- The error message:

Error: unable to flush session: session is not currently able to synchronize

indicates that Mutagen (the tool Garden uses for code synchronization) is unable to perform a sync operation because the session is in a state where it cannot synchronize. This is often related to lingering or stuck Mutagen processes, or a mismatch in the state of the sync daemon. Recommended steps to resolve: 1. Check for and kill lingering Mutagen processes: Run the following command to terminate any existing Mutagen processes:

sh
   kill -9 $(pgrep mutagen)

This is a common workaround for sync issues and is recommended by both the Garden team and community members when encountering similar errors [Discord thread](). 2. Stop the sync daemon: From your project root, stop the sync daemon to ensure a clean state:

sh
   garden util mutagen daemon stop

If you have recently upgraded or downgraded Garden, or switched sync modes, you may need to stop both the old and new daemons:

sh
   GARDEN_ENABLE_NEW_SYNC=false garden util mutagen daemon stop
   GARDEN_ENABLE_NEW_SYNC=true garden util mutagen daemon stop

[See official troubleshooting steps]() 3. Redeploy with sync: After ensuring all Mutagen processes and daemons are stopped, redeploy your services with sync enabled:

sh
   garden deploy --sync

If the problem persists after these steps, there may be a deeper issue with the sync session or your environment. In that case, you can use the following command to list all active syncs and further diagnose:

sh
garden util mutagen sync list

[Reference: List active syncs]() Summary: This error is most often resolved by stopping all Mutagen processes and daemons, then redeploying. If you continue to see the error, please provide additional logs or context for further troubleshooting. If you need more help, let me know what you see after following these steps! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
