P2 Dashboard Web Goes Down After hermes update — v0.18.0 Regression, python Command Missing (#57790)
Executive Summary
Updating Hermes Agent to v0.18.0 on Ubuntu 24.04 reportedly breaks the web dashboard entirely: the dashboard URL becomes inaccessible after hermes update, restarts do not recover it, and the environment shows python: command not found. With two independent same-day reporters on the same OS family, this looks less like a one-off machine problem and more like a real post-update regression path.
Observed Failure Pattern
- User runs
hermes updateto move to v0.18.0. - Most of Hermes continues to work.
- The dashboard URL becomes inaccessible (“website not found”).
- Restart attempts do not restore the web dashboard.
- The shell environment also reports
python: command not found, suggesting path or runtime damage during update.
The pairing of a broken dashboard and a missing python command hints that the update path may be clobbering environment assumptions rather than failing only at the UI layer.
Why This Matters
| Dimension | Severity | Detail |
|---|---|---|
| Upgrade Safety | HIGH | Users expect updates to improve the system, not take down the dashboard surface entirely. |
| Dashboard Reliability | HIGH | This adds to a growing stack of dashboard and post-update regressions already visible on the site. |
| Root-Cause Suspicion | HIGH | The missing python command suggests the update may disrupt environment configuration, not merely the dashboard process. |
| Regression Confidence | MEDIUM | The issue is marked duplicate of #57786, and both landed within hours on Ubuntu 24.04. |
Dashboard / Post-Update Regression History
| Issue | Severity | Description |
|---|---|---|
| #50889 | P2 | Dashboard auth under reverse proxy returns 404 |
| #57786 | P2 | Dashboard web stopped working on Ubuntu 24.04 |
| #57790 | P2 | Dashboard down after update, with python missing from environment |
⚠️ Pattern: dashboard regressions are now appearing both in proxy/front-door scenarios and in local post-update flows. If #57786 and #57790 share a root cause, the v0.18.0 update path may be destabilizing the dashboard stack on Ubuntu 24.04 in a way users only discover after upgrading.
Related Context
The duplicate relationship matters because #57790 does not stand alone. Two separate reporters hit the same dashboard failure within hours on the same operating system family. The research dispatch also notes a possible tie to #56894, where oversized log files may contribute to disk-space exhaustion and cascading failures. Even if that turns out not to be the primary cause here, the update path clearly lacks a graceful failure story.
