Error message

An error occurred!

What it means

error_translation() (src/translations/translations.rs:1090) returns the localized generic banner 'An error occurred!' used by the GUI's waiting page (src/gui/pages/waiting_page.rs:38) whenever sniffer.pcap_error is set. The banner is not an error itself: it is prefixed above the concrete pcap error string, which was captured earlier as CaptureContext::Error(e.to_string()). It tells the user packet capture could not start or continue.

Solutions

1. Read the second paragraph under the banner — it is the raw error string (e.g. 'libpcap error: permissions problem') and identifies which of the three failure classes it is.
2. If it is a permissions error, restart with elevated privileges or grant the binary CAP_NET_RAW (Linux), run as admin/Npcap user (Windows).
3. If the error mentions the filter, re-enter or clear the BPF filter text and restart the run.
4. If the error mentions the output file, pick a writable .pcap path or disable pcap output.
5. If the adapter disappeared, reopen adapter selection and pick a currently active device.

When it happens

Trigger: The waiting page renders this text when CaptureContext construction failed: device open failure (permissions, missing adapter — error 7), BPF filter rejection (error 8), or output pcap savefile creation failure (error 9). It shows when capture hasn't started (tot_packets == 0 and pcap_error present) and stays until the user changes capture settings and restarts.

Common situations: Launching Sniffnet without capture privileges (most common); selecting a network adapter that was unplugged or renamed after app start; typing an invalid BPF filter in the filter panel; choosing a pcap output path in a read-only directory; opening a corrupted or non-pcap file as the capture source.
