sensors

Posted on August 2, 2021 by ServerOk

sensors command shows data from various sensors on your computer like CPU temperature, voltage, etc… To install lm-sensors package, run

apt install lm-sensors

1	apt install lm-sensors

To see sensor data, run the command “sensors”.

boby@sok-01:~$ sensors

lspci command is used to list PCI devices on your computer. To see all lspci command-line options

root@first-vm:~# lspci help
Usage: lspci [<switches>]

Basic display modes:
-mm		Produce machine-readable output (single -m for an obsolete format)
-t		Show bus tree

Display options:
-v		Be verbose (-vv or -vvv for higher verbosity)
-k		Show kernel drivers handling each device
-x		Show hex-dump of the standard part of the config space
-xxx		Show hex-dump of the whole config space (dangerous; root only)
-xxxx		Show hex-dump of the 4096-byte extended config space (root only)
-b		Bus-centric view (addresses and IRQ's as seen by the bus)
-D		Always show domain numbers
-P		Display bridge path in addition to bus and device number
-PP		Display bus path in addition to bus and device number

Resolving of device ID's to names:
-n		Show numeric ID's
-nn		Show both textual and numeric ID's (names & numbers)
-q		Query the PCI ID database for unknown ID's via DNS
-qq		As above, but re-query locally cached entries
-Q		Query the PCI ID database for all ID's via DNS

Selection of devices:
-s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]	Show only devices in selected slots
-d [<vendor>]:[<device>][:<class>]		Show only devices with specified ID's

Other options:
-i <file>	Use specified ID database instead of /usr/share/misc/pci.ids.gz
-p <file>	Look up kernel modules in a given file instead of default modules.pcimap
-M		Enable `bus mapping' mode (dangerous; root only)

PCI access options:
-A <method>	Use the specified PCI access method (see `-A help' for a list)
-O <par>=<val>	Set PCI access parameter (see `-O help' for a list)
-G		Enable PCI access debugging
-H <mode>	Use direct hardware access (<mode> = 1 or 2)
-F <file>	Read PCI configuration dump from a given file

Skype public key is not available

Posted on June 29, 2021 by ServerOk

I have Ubuntu 20.04 computer with skype installed. When I update software using apt update, I get an error

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://repo.skype.com/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1F3045A5DF7587C3
W: Failed to fetch https://repo.skype.com/deb/dists/stable/InRelease  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1F3045A5DF7587C3
W: Some index files failed to download. They have been ignored, or old ones used instead.

To fix this error, delete the key

sudo apt-key del 1F3045A5DF7587C3

1	sudo apt-key del 1F3045A5DF7587C3

Add the key again with

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1F3045A5DF7587C3

1	sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1F3045A5DF7587C3

Now you can update software with

sudo apt update
sudo apt upgrade -y

1 2	sudo apt update sudo apt upgrade -y
