I recently installed Memgraph and Memgraph Lab from the official downloads page and encountered Memgraph failing to start- this was due to Neo4j using the same port (though the error logs were completely, entirely, absolutely useless).
Memgraph Lab did start exactly once, but it refused to start after I removed it with apt and reinstalled it with dpkg.
Once again I am finding the error logs unhelpful. Things I’ve tried:
-
Disabling
apparmor(though Memgraph Lab doesn’t appear to be underapparmor‘s jurisdiction). -
Installing Memgraph Lab via the “Direct Download Links (https://memgraph.com/docs/getting-started/install-memgraph/direct-download-links) – using the .deb package for Ubuntu 24.04 AMD64 of course.
-
Checking the
systemctllogs -
Invoking
memgraph-labfrom Terminal. This gives the following output:
LaunchProcess: failed to execvp:
/opt/Memgraph
Trace/breakpoint trap (core dumped)
/opt/Memgraph indeed does not exist, so I suspect this is the issue; however, the .deb installers don’t seem to be creating it. Presumably it was created the first time when Memgraph Lab successfully launched? But then why was it deleted and why can’t it be recreated?

Launching memgraph-lab with memgraph-lab --no-sandbox works. I feel like this is an issue that the Memgraph Lab devs have to work through, but I think this is an adequate fix for now.
