Two VLC icons can come from separate package routes, such as a distribution package and a snap. The duplicate is not necessarily an installation failure.
First identify which edition holds the setup you use. Removing one blindly can make familiar preferences disappear while leaving the other copy untouched.

Compare installed package records
Inspect the application manager and the relevant package tools for the exact VLC installations. Record the source and version for each. The icon and display name can be identical even when the packages are separate.
Use read-only package information first. A command that lists installed packages is a different action from one that removes or purges them. Do not paste a cleanup command before establishing which package it targets.
Open and identify each launcher carefully
Launch one copy at a time and read its About/version information. Note the launcher used and any distinct setup. Close it before opening the other to avoid confusing a reused window with a second process.
If local preferences matter, preserve them through a documented route. Do not assume the two packages share configuration or that a backup made in one can be restored into the other without qualification. Package confinement and data paths can differ.
Decide which supported route you want to maintain. Use its genuine publisher and Ubuntu guidance rather than choosing only by a higher number displayed in a search result.
Remove only the identified unwanted edition
When removal is justified, use the package manager that owns that edition and review the confirmation. Keep purge, snapshots and dependency cleanup separate unless their consequences are understood. Do not manually delete broad application or home folders.
Afterward, open the remaining launcher and verify the intended version and setup. A media player’s installation state does not provide an IPTV USA account or establish service compatibility. The result here is a clear single software route, not a playback certification.
Useful answers
Do two identical icons always point to the same VLC installation?
No. Different package routes can create separate launchers with similar artwork.
Should I delete both and start again?
First identify the source, version and local setup. A targeted removal can avoid unnecessary restoration work.
