Public bug reported:

[Impact]

Currently openvpn in Jammy is broken when FIPS is enabled. The TL;DR reason is 
that openvpn 2.5 does not support openssl 3 very well. There were a number of 
fixes in openvpn 2.6 to fix this.
Explaining a bit more the basic issue is that openssl 3 does not allow the use 
of the MD5 algorithm for random number generation in FIPS mode and openvpn 2.5 
is still using it (LP bug #2091575). There are also other issues, for example 
that openvpn sees no available ciphers when FIPS is enabled which can be easily 
tested as running 

openvpn --show-ciphers

returns nothing (LP bug #2077769).
I have a patch for openvpn 2.5 to fix this which I tried to SRU in bug #2077769 
but failed to get sponsored as it is a significant change. The sponsor 
suggested backporting instead as the issue does not affect non-FIPS systems and 
so they can keep using the current package.

[Scope]

From Noble (2.6.12-0ubuntu0.24.04.1) to Jammy (currently
2.5.11-0ubuntu0.22.04.1)

[Other Info]
 
My original SRU patch also fixed bug #2086809. This is not a code patch as only 
affects package testing. This should be SRUd by itself.
