Does libliv have a custom apt repo to update from, or should I compile the recent version/manual install it? Also, do I have to recompile my ardour binary as well?
Thanks by the way!
Since liblilv’s API has not changed, you don’t need to recompile Ardour.
For a 2nd opinion, you could also try an official binary or nightly https://nightly.ardour.org/ (demo is fine to test, and it can be installed in parallel to distro versions).
I tried the nightly demo. It gave me this error. The calf reverb and flanger plugins are commonly used in other sessions without issue.
Session “/hyperdrive/recording/album-seven-tabs/magma-den (snapshot magma-den)” did not load successfully:
Cannot initialize session/engine: Port registration failed.

I attempted to review all the reverb flanger plugins and it still crashed. I’m going to uninstall libliv (since I manual installed it) and restart my computer to see if it’ll do anything
Calf failing to work isn’t to surprising, sorry.

Ardour is ignoring all of my lv2 plugins. It’s acting as if they are not there. It’s no longer crashing however.
Without liblilv (LV2 library) you will not be able to use any LV2 plugins.
–
Also calf plugins are not longer supported by Ardour, and those plugins will also soon be removed from various major distros (see Ardour 8.4 Calf plugins [ERROR]: failed to instantiate LV2 GUI - #4 by x42)
I installed the updated version manually and recompiled ardour. It still won’t detect an lv2 files.

Run lv2ls to see if you still have some LV2 plugins installed.
If you do, start your freshly compiled Ardour from the terminal and see if it complains about anything.
Doesn’t show any of the ones i installed like surge, lsp, etc.
How do I get lv2 to detect?
rave@rave-machine:~$ lv2ls
http://lv2plug.in/plugins/eg-amp
http://lv2plug.in/plugins/eg-fifths
http://lv2plug.in/plugins/eg-metro
http://lv2plug.in/plugins/eg-midigate
http://lv2plug.in/plugins/eg-params
http://lv2plug.in/plugins/eg-sampler
http://lv2plug.in/plugins/eg-scope#Mono
http://lv2plug.in/plugins/eg-scope#Stereo
Where are your plugins installed?
From the Ardour manual:
LV2 plugins are folders/directories. They need to be installed in either /usr/lib/lv2, /usr/local/lib/lv2 or a directory mentioned in the local LV2_PATH environment variable.
One caveat to that is some distributions may modify the search path. Specifically Fedora uses /usr/lib64/lv2 as the system search path and /usr/local/lib64/lv2 for the locally compiled search path.
I think that is done by patching the distribution version of lilv tools, but I have not found a way to make lv2ls print the search paths it is using.
Run
find /usr -name manifest.ttl ; find /opt -name manifest.ttl ; find ~/.lv2 -name manifest.ttl
to see where your plugins are installed
If you uninstalled the lilv package that came with Ubuntu then it probably removed any LV2 plugins that you had “apt installed” as well.
A hack for that is to run something like
strace lv2ls >& /tmp/LOG
grep "openat(AT_FDCWD" /tmp/LOG| grep lv2

I got ardour to scan the plugins, but it says they’re all “Stale”
I have manual reinstalled the plugins.
What is the ardouri8 plugin manager cache directory? I manually compiled the most recent liblilv directory because anything less than 0.24.24 caused the crashing bug. Did that have a side effect/
I use Ubuntu 24.04 LTS are the plugins at a nonstandard directory?

Stale status is defined as “A plugin changed on the disk but hasn’t been re-scanned by Ardour yet.”
What happens when you click the “Re-scan All” button?
Hopefully nothing. The plugin manager is only for VST2/3 and AU plugins that require scanning.
LV2 plugins are indexed by meta-data at application start (though rescan should clean out the log of previously found, now stale, LV2s).
That is why I was curious, since the plugin manager showed “Stale” state for all of the listed LV2 plugins.
Nothing happens. How do I trigger an LV2 rescan?
As mentioned in my earlier post the plugin manager (the dialog in the screenshot you provided) has several buttons on the left hand side, one of which is labeled “Re-scan All.” Just click that button.
See above
LV2s are always and unconditionally indexed when loading a session or starting Ardour.
Do you think the program’s inability to index could be from two different liblilvs in conflict?
