[SOLVED] Ubuntu update error

Operating Systems & Open Source Linux
1

Whenever I do a sudo apt update && sudo apt full-upgrade I get the following error:

error.png916x348 76.8 KB

However, when I try to remove android-tools-adbd I get a very similar error:

Anyone know anything about how to fix this?

2

Does "apt-get -f install" do something?
Does "ps -aux | grep adb" show something?

3

apt -f install ignores the package and ps -aux | grep adb shows abd not running.

after funning adb start-server, this shows up in ps -aux | grep adb:
thomas 5012 0.0 0.0 112380 2672 pts/2 Sl 14:48 0:00 adb -P 5037 fork-server server
apt -f install still ignores android-tools-adbd and error while upgrading still occurs.

4

sudo apt-get remove --purge -y android-tools-adbd
followed by
sudo apt-get autoclean

5

Same error as before. I think this might be a problem with systemd (or whatever) being unable to stop a service that doesn't exist (android-tools-adbd.service). How would one go about creating a dummy service to be stopped to keep apt happy?

sudo systemctl disable foo.service

That's the problem. android-tools-adbd.service doesn't exist anywhere on the drive.

Solved! Created a dummy service called android-tools-adbd.service ( http://patrakov.blogspot.com.au/2011/01/writing-systemd-service-files.html )
Contents:

[Unit]
Description=adbd dummy service

[Service]
ExecStart=/bin/sleep 10000000

[Install]
WantedBy=multi-user.target

copied to /etc/systemd/system/ and ran systemctl start android-tools-adbd.service to start it and was successfully able to remove android-tools-adbd then deleted the service.

Everything's back to normal.
