+qemu 1:6.0+dfsg-2expubuntu2: Fail to build against OpenSSL 3.0
+
+Issue discovered after doing a "No-change rebuild" upload to Jammy while working at the liburing2 migration (LP: #1944037). 
+
+Full build log:
+
+https://launchpadlibrarian.net/570888790/buildlog_ubuntu-jammy-amd64.qemu_1%3A6.0+dfsg-2expubuntu3_BUILDING.txt.gz
+
+Failure mode:
+
+/<<BUILDDIR>>/qemu-6.0+dfsg/roms/skiboot/libstb/create-container.c: In function ‘getPublicKeyRaw’:
+/<<BUILDDIR>>/qemu-6.0+dfsg/roms/skiboot/libstb/create-container.c:85:17: error: ‘EVP_PKEY_get1_EC_KEY’ is deprecated: Since OpenSSL 3.0 [-Werror=deprecated-declarations]
+
+Also note that:
+
+cc1: all warnings being treated as errors
+
+Upstream skiboot [1] still uses EVP_PKEY_get1_EC_KEY in master, and don't have an open issue about this. To be filed once we setup a reproducer that builds skiboot "standalone", outside of the qemu source tree.
+
+For the moment we have to relax the severity of that deprecation error, likely appending a -Wno-deprecated-declarations somewhere in d/rules.

+
+Messing around with someone elses crypto functions rarely is good ;-)
+So I reported it Upstream at the skiboot project as:
+=> https://github.com/open-power/skiboot/issues/271
+
+This bug was fixed in the package qemu - 1:6.0+dfsg-2expubuntu4
+
+---------------
+qemu (1:6.0+dfsg-2expubuntu4) jammy; urgency=medium
+
+  * d/p/lp-1952448-relax-skiboot-gcc-deprecation-errors.patch:
+    add patch to workaround FTBFS when building against OpenSSL 3.0.
+    Thanks to Christian Ehrhardt (LP: #1952448)
