Remarkably, Guacamole worked fine, except for uploads! I adjusted the

Reloaded apache and everything is working properly.
Now to try and make some dangerous OSs print! :P

This is embarrassing, but I just found a clue…
Bypassing the apache2 reverse proxy cures this issue. Any guesses on
what config in apache2 might fix me up…

Hi all –
I’m hoping someone can help me address the error “failed to load
"guac-common-svc"” which prevents downloads from working in RDP via
Guacamole.
This is a new installation running on Ubuntu 22.10 and Guacamole 1.5.0.
I’m not sure what information is helpful, so here’s some facts: J
Make thinks everything is happy:
guacamole-server version 1.5.0
------------------------------------------------
Library status:
freerdp2 ............ yes
FreeRDP plugins: /usr/lib/x86_64-linux-gnu/freerdp2
That directory exists, as does the plugin directory beneath:
$:/ # ls /usr/lib/x86_64-linux-gnu/freerdp2/ -al
total 512
drwxr-xr-x 2 root root 4096 Mar 27 17:21 .
drwxr-xr-x 46 root root 49152 Mar 27 17:31 ..
-rwxr-xr-x 1 root root 1143 Mar 20 22:13 libguacai-client.la
-rwxr-xr-x 1 root root 371344 Mar 20 22:13 libguacai-client.so
-rwxr-xr-x 1 root root 1197 Mar 20 22:13 libguac-common-svc-client.la
-rwxr-xr-x 1 root root 82440 Mar 20 22:13 libguac-common-svc-client.so
Probably not relevant, but I’m using apache2 as a reverse proxy. The
only things on the box are apache2/tomcat9/guacamole and mysql for auth.
I believe the only “weird” thing is that Guacamole is running under user
“guacd” because I had this issue:
https://kifarunix.com/install-guacamole-on-debian-11/#fix-rdp-security-negotiation-failed
<https://kifarunix.com/install-guacamole-on-debian-11/#fix-rdp-security-negotiation-failed>
Changing the user for guacd solved that problem.
The only thing that seems obvious to me is that the error references a
plugin (guac-common-svc) that does not explicitly exist… However since
Guacamole built the plugin I’m hesitant to mess with it….
Everything works exactly right except downloads!
Anyone have ideas?
