Install Gqrx SDR on Ubuntu 20.04 LTS

[Nick Mortel]

Hi all,

Is the Install Gqrx SDR on Ubuntu LTS on https://gqrx.dk/ okay for install on latest ubuntu 20.04 ? New user ubuntu installed on laptop with windows removed (OS is ubuntu, nothing else onboard).

Thanks in advance - Nick Mortel

[Nick Mortel]

.........I get this back on Terminal when I attempt .....

sudo apt-get install gnuradio gqrx
[sudo] password for nickmortel:
E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 8511 (apt-get)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

[Adrian Scripcă]

Hi Nick,

Quickest fix, (in case you didn't reboot the system) would be to simply run `sudo kill -9 8511` and then try again the installation through apt. Most likely an update is being ran by the system in background.

All the best,

Adrian

No, no luck with that.

[Richard Bown]

This should have gone to the list

Hi I can confirm Ubuntu 20 has a most annoying "unattended backup" running

You need to kill that process, and

run ps ax | grep unattended

kill the earliest instances of the unattended updates as it has a
tendency to respawn.

DO not just kill the last unattended updates, it WILL respawn.

Really is a PITA, like most things with Ubuntu 20 unfortunately

If you want to remove this PITA feature in ubuntu20

the magic line to type is

sudo apt remove unattended-upgrades

[Adrian Scripcă]

Alternatively, you can retry after a short while; give the upgrader the chance to finish.

only if you like watching paint dry, it takes ages and ages and ages and
ages ,

you could watch half a dozen box sets and it would still be doing it . :)

even go to bed, get up in the morning , watch more box sets, and it
would still be going

It may finish when there is no more covid

E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 8511 (apt-get), it means a process is using the APT-GET feature and first must be stopped before you can proceed, else you get the ERROR message.
