Using systemctl start unifi on a fresh install results in WARN Unable to load properties from '/usr/lib/unifi/data/system.properties' - /usr/lib/unifi/data/system.properties (No such file or directory). The symlink in /usr/lib/unifi/data exists and it points into a real location in /var/lib/unifi/data which is owned by the unifi account.

I use an actual override.conf for the unifi.service to pin it to jre17

[Service]
ExecStart=
ExecStart=/usr/lib/jvm/java-17-openjdk/bin/java --add-opens java.base/java.time=ALL-UNNAMED -jar /usr/lib/unifi/lib/ace.jar start
ExecStop=
ExecStop=/usr/lib/jvm/java-17-openjdk/bin/java -jar /usr/lib/unifi/lib/ace.jar stop

So proper depends=(jre17-openjdk-headless) would be possible without touching the default system java version.

As an addition thought... since Arch only officially supports java 17 (as LTS) and 21 as stated in the wiki article and I can't even get the AUR versions of 18 and 19 to build in a clean chroot, should the PKGBUILD be simply restricted to 17 with a dependency java-runtime-headless=17?

pikl commented on 2023-12-03 09:14 (UTC)

Following up on comments from pnedkov and GaryScottMartin, it looks like Unifi 8.0.7 introduced a restriction on using java 21. Since the core openjdk packages are at 21 this is more likely to be a issue with new installs (as pnedkov discovered) or if you clear out java versions (as GaryScottMartin discovered).

If run with java 21, unifi 8.0.7 fails to launch and /var/log/unifi/server.log contains the following:

[2023-12-03 08:59:39,797] <launcher> INFO  launcher - Initializing on Linux(6.6.3-arch1-1), jre21(21)
[2023-12-03 08:59:39,797] <launcher> ERROR launcher - Java 21 is not supported!

Fix as pnedkov did by installing an older version of your preferred java package (e.g. 17) and setting it as the default using the archlinux-java command.

I'm not sure how the PKGBUILD should be altered to reflect this new restriction. I experimented with adding java-runtime-headless<21 to the dependencies with the existing java-runtime-headless>=17. Unfortunately these are treated separately as dependencies so when installing with pacman you get two prompts and can end up installing two versions - with an incompatible version becoming the default.

Today I set up a brand new Arch Linux host with unifi and stumbled on the same problem GaryScottMartin has described in the previous post. Then I examined glennr's script (https://get.glennr.nl/unifi/install/unifi-8.0.7.sh) and I noticed that the latest java he is installing is version 17. So, I installed it manually and now unifi starts successfully.

Based on above comment by pnedkov, I reinstalled jre17-openjdk. Unifi still failed to start until I set the default Java installation to java-17-openjdk. I searched for a way to get Unifi to use a Java installation other than the default, but didn't find one.

=============================================================

I have had unifi installed and running on my system for a couple of months, but it now fails on startup.

I have jdk-openjdk installed and set:

[user@host ~]$ archlinux-java status
Available Java environments:
  java-21-openjdk (default)

I have recently uninstalled older versions of Java from the system during a security cleanup.

Here are listings of the two directories named in the systemctl status:

[user@host ~]$ ls /usr/bin/java
lrwxrwxrwx - root 19 Jan 04:33 /usr/bin/java -> /usr/lib/jvm/default-runtime/bin/java*
[user@host ~]$ ls /usr/lib/unifi/lib/ace.jar
.rw-r--r-- 16M root 22 Nov 01:08 /usr/lib/unifi/lib/ace.jar

Suggestions?

I had to update my unifi systemd unit with the new ExecStart argument added a few commits ago before the UI would work again.

I can't get this working since a recent update. I tried wiping out /var/lib/unifi/data/db and using mongobin-44 and mongobin-50 using java17 but I keep getting:

Exception in thread "launcher" java.lang.NullPointerException: Web context failed to initialize
Oct 04 20:29:11 darch java[33079]:         at java.base/java.util.Objects.requireNonNull(Objects.java:235)

I even tried downgrading to 7.4.162 but it's the same story. I tried removing /var/lib/unifi/data/keystore, same story.

This is my system.properties which is the only file I've modified...

reporter-uuid=...
unifi.http.port=8089
debug.device=warn
debug.mgmt=warn
unifi.https.port=8090
debug.setting_preference=auto
is_default=false
debug.system=warn
uuid=...
unifi.https.sslEnabledProtocols=TLSv1.2
debug.sdn=warn

Any idea what might be wrong?

Edit:

I had overriden the systemd unit to hardcode the jvm path, but I missed a new parameter needed --add-opens java.base/java.time=ALL-UNNAMED

Just informational -- I upgraded to the 7.5.176-1 release and was getting the 404 page after that upgrade. I was on mongodb44-bin as well.

I tried pointing systemd's service file to java11, 17, and 21 first but none had luck. If it was pointed to java11 it would say it was compiled with a more recent version and would never start, for me. 17 and 21 would let the service start but gave the 404 page.

Then I tried monogdb36-bin and 50-bin and didn't have any luck. After trying those two, I reverted back to my original version of 44-bin and then it worked, with the systemd service file using java17.

So I guess ultimately in my case reinstalling mongodb44-bin was the trick for some reason, along with making sure the unifi system file pointed to java17
