GitLab error OpenSSL::Cipher::CipherError () in app/controllers/admin/application_settings_controller.rb:40:in `update'

The issue

It happened after secrets file was lost during GitLab upgrade.

The case described in documentation When the secrets file is lost

But not completely clear.

From log file /var/log/gitlab/gitlab-rails/production.log:

ACPI Error: AE_NOT_EXIST, Evaluating _PMM (20190816/power_meter-325)

The same problem on an HP server and there is a smarter solution found here: https://www.novell.com/support/kb/doc.php?id=7010449

Instead of disabling sensors in netdata altogether, you can just disable the acpi_power_meter kernel module, which doesn't work anyway on affected HP servers due to a BIOS bug. This way netdata can still get the temperature readings.

This is how you can disable the module immediately:

sudo modprobe -r acpi_power_meter

And this is how you make it permanent:

# script created for reading SMS messages from 3G modem connected to PC
# 1) it looks for modem
# 2) reads all SMS messages from modem
# 3) prints all found SMS messages to stdout only if total messages count
# greater than SMS_STORE_COUNT (default is 3)
# 4) save all but SMS_STORE_COUNT messages to txt files and
# delete them from modem
