Update from previous version failed due to there not being a ui release variant (this is ok I suppose though you might want to mention it in release notes):

codebase-memory-mcp update
codebase-memory-mcp update (current: 0.9.0)

Update available: 0.9.0 -> v0.10.0
Which binary variant do you want?
  1) standard  — MCP server only
  2) ui        — MCP server + embedded graph visualization
Choose (1/2): 2

Probably selecting 1 may work, I didn't test but just tried to reinstall using the script installer:

Downloading the tar.gz directly and running install.sh manually also fails.

Thanks for the thorough report, @iandol — you found two distinct bugs, and both are now slated for v0.10.2, the next fix release.

1. The variant chooser is obsolete — and not just in your old binary. As of v0.10.0 there is only ONE build per platform, with the graph UI always embedded; the ui-* archives no longer exist, which is why your "2) ui" choice 404s. What we hadn't realized until your report: the chooser still ships in current binaries too, offering a "ui" option that can only 404 and a "standard" option that quietly is the full UI build. Two fixes coming: the chooser is being removed entirely (update just downloads the one real archive), and we'll attach ui-*-named alias assets t…

Thanks! There was no log in ~/.cache/cagelab-memory-mcp/logs -- my ~/.cache parent directory has permissions of 775 is that what you are referring to, this is group writable, and it shouldn't be? Earlier versions of CBM had never flagged that I need to change permissions of the cache folder, and the current error is cryptic.

OK, I've now set ~/.cache to 755 and indeed the installer gets further than before, although now errors on agent setup:

Exception: bash exited with 1

I also now get a activation-events.ndjson but it doesn't give any more detail on what failed...

As an aside the update command is giving out-of-date or inconsistent advice:

> codebase-memory-mcp --version
codebase-memory-mcp 0.10.0

> codebase-memory-mcp update -y
codebase-memory-mcp update (current: 0.10.0)

The update runs from install.sh, not from this process. Run

  bash "/home/cog5/.local/bin/install.sh"

It downloads the latest release, verifies its checksum, and replaces
this binary in place. install.sh is idempotent, so re-running it IS
the update; pass --ui for the UI build.

There is no ~/.local/bin/install.sh after the installer. The install does not support a --ui option any more.

Thanks for the thorough report, @iandol — you found two distinct bugs, and both are now slated for v0.10.2, the next fix release.

1. The variant chooser is obsolete — and not just in your old binary. As of v0.10.0 there is only ONE build per platform, with the graph UI always embedded; the ui-* archives no longer exist, which is why your "2) ui" choice 404s. What we hadn't realized until your report: the chooser still ships in current binaries too, offering a "ui" option that can only 404 and a "standard" option that quietly is the full UI build. Two fixes coming: the chooser is being removed entirely (update just downloads the one real archive), and we'll attach ui-*-named alias assets to releases so older 0.9.x binaries' updaters work again without you doing anything. Until then: choosing 1) standard gets you the complete product, UI included.

2. The install.sh failure is a real bug we're actively hunting — failed to stage install candidate: activation transaction I/O failed is also reported on WSL2 (#1535), and your report tells us it's broader than WSL2. Our current suspicion is the staging transaction's filesystem assumptions (cross-device renames on network/overlay filesystems). If you can share what filesystem your home / ~/.local/bin and /tmp are on (df -T ~/.local/bin /tmp), that would help us pin it — no worries if not.

Also worth grabbing when you retry: v0.10.1 fixes an important MCP output bug in 0.10.0 (tool results rendering empty in MCP clients).

Sorry for the bumpy upgrade, and thanks again — reports like this, with full transcripts of both paths, are exactly what makes fixes fast.

Both issues are fixed in v0.10.2, released just now: https://github.com/DeusData/codebase-memory-mcp/releases/tag/v0.10.2

The install failure was a permission policy, not I/O: a group-writable ~/.local (or any parent) was refused outright. Parents are now warned about rather than blocked, the install directory itself stays owner-private, and refusals name the directory and mode instead of claiming an I/O error.
The obsolete ui/standard chooser is gone — and releases now also publish ui-*-named copies of each archive, so updaters in already-installed 0.9.x binaries (like the one that 404'd for you) resolve again with nothing required from you.

Thanks again for the detailed transcripts of both paths — they made this considerably faster to pin down.

Heads-up for anyone still following this thread: v0.10.3 is building now, and it fixes the remaining install failures that v0.10.2 did not.

The one most likely to have affected people here: the daemon refused to start when any ancestor of its cache directory was group-writable — the same rule v0.10.2 removed on the installer side, in a sibling check that was missed. A group-writable ~ or ~/.cache is completely ordinary (WSL2 ships 0775, as do several distro skeletons), so for those users the daemon was permanently unusable, with nothing to close and nothing a reboot could fix.

Worse, the error message was inventing its own evidence: that refusal path set no error code, so it printed whatever errno happened to hold and reported ENOENT for a permission decision. At least one person went looking for a missing file that was there the whole time. Both are fixed, with tests in both directions — world-writable ancestors are still refused, and the private directory itself is still owner-only.

Also in v0.10.3: update --ui works again (v0.10.2 turned it into a hard error), OpenCode installs go into an existing opencode.jsonc, Codex receives CBM_CACHE_DIR, and the installed skill file no longer breaks strict YAML parsers.

Thank you to everyone in this thread who kept reporting through three releases of install trouble — nearly every fix above came from someone posting an exact error rather than giving up.
