The packages I see for Ubuntu 22.04 are all 3.x:
https://packages.ubuntu.com/search?keywords=libssl-dev
Are you sure you're using 22.04? Could there be a mismatch between the
headers installed by libssl-dev and the actual installed version of OpenSSL?

Thanks Nicky & Mike !
I have tried firstly what Nichy said and after all, the issue remains
the same. Checking openssl version, I see that I have 1.1.1n from March
2022 which I think it is the standard for Ubuntu 22.0.4 .
Any other stuff to try?

Just tried installing guacamole-server 1.5.2 on a fresh Ubuntu 22.04
instance, and things appear to work correctly. I see no undefined
symbol
errors.
The FIPS_mode() function is part of OpenSSL but is specific to OpenSSL
1.x. It was deprecated and removed from OpenSSL 3.0, so the
guacamole-server code uses that function only if built against an older
OpenSSL:
https://github.com/apache/guacamole-server/blob/83ca7aa16b49830b5adb5a0ce60082b385163934/src/libguac/fips.c#L23-L45
<https://github.com/apache/guacamole-server/blob/83ca7aa16b49830b5adb5a0ce60082b385163934/src/libguac/fips.c#L23-L45>
My guess would be that the version of OpenSSL present at build time was
older, and that the version was upgraded later to a version that lacks
FIPS_mode(). Rebuilding guacamole-server against the copy of OpenSSL
currently present should solve the issue.
