Dear Maintainer,

I spotted this bug using Ubuntu 26.04 but after browsing Ubuntu and Debian packages I believe the source of the problem is in Debian. I was able to confirm it also in Debian. For both, I use docker:
docker run -it ubuntu:26.04
docker run -ir debian:forky

I install lcov and the apt reports to install version 2.4-3, it is also visible in the package search engine for both Debian and Ubuntu.

But calling lcov --version shows on both:
$ lcov --version
lcov: LCOV version 2.0-1

and also:
$ dpkg-query -W lcov
lcov    2.4-3

On my Gentoo with lcov-2.4 it displays properly 2.4:
$ lcov --version
lcov: LCOV version 2.4-0

When I downloaded the sources from lcov github page, .version file shows:
VERSION=2.4
RELEASE=0

but for the one downloaded from Debian Search Package engine (lcov-2.4.orig.tar.gz), which seems to be repacked (I don't use Debian daily and don't know in details what is happening with source packages), it shows:
VERSION=1.14
RELEASE=1
FULL=1.14

which is even more confusing, why 1.14 and not 2.0.

For the original lcov-1.14 package from github, it indeed shows:
VERSION=1.14
RELEASE=1
FULL=1.14

But files size, Makefile, in the sources between upstream sources and Debian sources do not match between 1.14, 2.0, 2.4.

Also, this:
grep "our \$VERSION" /usr/lib/lcov/lcovutil.pm
our $VERSION   = "2.0-1";


It is all confusing. Can it be that when the sources were repacked (are they repacked?) were somehow messed?

Regards,
Rafał
