Issue with Guacamole 1.5.2 native build
I followed the below steps to generate guacd (Guacamole 1.5.2) .so files.
So, I can deploy it on another machine if I wish.
I took a Linux machine with Ubuntu 20.04.6 installed. Followed the Guacamole
Native installation documentation
<https://guacamole.apache.org/doc/gug/installing-guacamole.html> and
installed the libraries specified in the documentation.
Note: Installed all required libraries using apt install only.
I have copied the generated libs and launcher files into another Linux
machine of the same OS version (installed required libraries).
I was able to start the guacd service without errors. But, when I tried to
use SSH / RDP, I faced issues below.
SSH:
1. Password-based login is working fine.
2. Key-based authentication is not working.
*Error: guacd[21666]: Public key authentication failed: Unable to extract
public key from private key.*
Later, I tried with the libssh2-1.11.0 version (1.8.0 is the default in
Ubuntu 20.04.6), and Then I got the below error.
guacd[23242]: Public key authentication failed: Callback returned error
RDP:
Getting disconnected after a successful login but no display. (error if I
provide wrong login details)
*kernel: [15747103.155263] guacd[16970]: segfault at 0 ip 00007ff8518ccbc0
sp 00007ff84a7fb8a8 error 6 in libc-2.31.so
<http://libc-2.31.so/>[7ff851763000+178000]*
I followed the same steps for the Guacamole 1.4.0 version, where SSH/RDP
both are working fine.

Have you verified that the library versions are identical? You can
also check the .so files manually with "ldd -r
/path/to/guac/lib/library.so" which will attempt to resolve dynamic
dependencies and report either missing libraries or missing symbols.

For the RDP issue, you'd likely need to gather the stack trace
(backtrace) from the core dump to determine what's going on, here.

Public key authentication failed: Unable to extract public key from private key
This is OpenSSH issue: https://security.stackexchange.com/questions/226131/openssh-declares-ssh-rsa-deprecated-what-do-i-do-next
We find Debian 10/11 failed with same error Guacamole SSH to Ubuntu 22.04.
* Debian 12 has latest SSH libs and is OK
Try installing Guacamole 1.5.2 on Ubuntu 22.04.
