I ran 16.04 since it was released as a fresh install, and about a month ago upgraded to 18.04 using the official upgrade mechanism. I've noticed this in syslog:

Sep 27 17:40:36 yavin systemd[1]: Starting Daemon for power management...

So upowerd cannot find libssl.so.1.0.2, sure enough:

$ ldd -v /usr/lib/upower/upowerd | grep 'not found'
 libssl.so.1.0.2 => not found
 libcrypto.so.1.0.2 => not found
 libcrypto.so.1.0.2 (OPENSSL_1.0.2d) => not found
 libssl.so.1.0.2 (OPENSSL_1.0.2d) => not found

Is upowerd still used in 18.04, and if so, how can I confirm which versions of it and libssl/libcrypto I have, which I need, and perhaps forcably re-install them?

Here's what I seem to have installed:

$ sudo apt list --installed | grep "libssl"

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libssl-dev/now 1.1.0h-2.0+ubuntu16.04.1+deb.sury.org+1 amd64 [installed,local]

And libcrypto:

$ sudo apt list --installed | grep "crypto"

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

This may have been a problem since before the upgrade. Without upowerd I have no battery level management and my laptop has powered down suddenly losing work a couple of times and I recall this happening before the upgrade also.

EDIT

As requested, output of apt policy upower:

upower:

EDIT 2

Asking apt to reinstall upower results in the same package being installed, and no change in apt policy upower output.

No diversions seem to be set up, and the libssl and libcrypto libraries are still not found by the upowerd binary:

$ dpkg-divert --list /usr/lib/upower/upowerd

$ ldd -v /usr/lib/upower/upowerd | grep 'not found'
 libssl.so.1.0.2 => not found
 libcrypto.so.1.0.2 => not found
 libcrypto.so.1.0.2 (OPENSSL_1.0.2d) => not found
 libssl.so.1.0.2 (OPENSSL_1.0.2d) => not found

EDIT adding comparison with fresh install of Ubuntu 18.04

Since @stephen-kitt mentioned upowerd isn't supposed to depend on libssl, I installed a fresh virtual machine with 18.04 and sure enough, the ldd list is different.

laptop with problem except from ldd -v /usr/lib/upower/upowerd

ibffi.so.6 => /usr/lib/x86_64-linux-gnu/libffi.so.6 (0x00007ff3f0466000)

/lib64/ld-linux-x86-64.so.2 (0x00007f4aabc8c000)

For some reason the laptop links against libssl and libcrypto, while fresh install links to libgnutls, libtasn1 and libgcrypt.

The fresh install still reports the same apt policy as the laptop:

$ apt policy upower
upower:
 Installed: 0.99.7-2
 Candidate: 0.99.7-2
 Version table:
 *** 0.99.7-2 500
 500 http://th.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
 100 /var/lib/dpkg/status

I've no idea why this might be.

Pretty soon I'm just going to reinstall the laptop (it has other issues like very long delays in apps like gedit loading) but it would be nice to figure out how this mess happened.

Somehow you’ve ended up with a version of /usr/lib/upower/upowerd which doesn’t correspond to the file contained in the upower package.

To fix this, re-install the package:

sudo apt install --reinstall upower

If that doesn’t help, check whether there are any diversions:

dpkg-divert --list /usr/lib/upower/upowerd

If that shows a diversion, check the corresponding package; you might need to upgrade or remove it.
