   What are the exact steps to reproduce on a fresh install? I tried on mantic with the steps provided and it passed:

   0export DEBIAN_FRONTEND=noninteractive && apt update && apt install git vim ccache -y && git clone https://github.com/bitcoin/bitcoin.git --branch=26.x  --depth=1 ./bitcoin-core && cd bitcoin-core && apt install build-essential libtool autotools-dev automake pkg-config bsdmainutils python3-zmq systemtap-sdt-dev     libevent-dev libboost-dev   -y   &&  ./autogen.sh && ./configure --disable-bench --disable-fuzz-binary --enable-debug --without-gui             --enable-suppress-external-warnings --disable-wallet   && make -j $(nproc)

   I can’t reproduce the issue either.

   What are the exact steps to reproduce on a fresh install?

   bitcoin-util doesn’t seem to be linked against libevent. It also doesn’t actually use that function. Normally, the linker would drop unused object files, but somehow it doesn’t in this user’s case. It shouldn’t be linking in that object (common/url.o) in the first place.
