How to install screenlets on Ubuntu 18.04?

apt 18.04 updates screenlets

The add-apt-repository command is located in software-properties-common. You need to install it first:

sudo apt-get install software-properties-common

Then you may want to remove or edit paths for problematic PPAs:

GetDeb.net is often down. You should follow this answer and edit corresponding sources.list.
The inameiname/stable PPA does not have files for Bionic (but have for Xenial). You should edit its sources.list and change bionic to xenial.

Then you will be able to update package lists and retry your procedure.

As the result you will get ScreenLets installed and can configure them with screenlets:

Note: for Ubuntu 16.04 LTS one can use official PPA - ppa:screenlets/ppa.

I want to install Screenlets and I tried the following bash:

#!/bin/bash
sudo dpkg -l python-wnck >/dev/null 2>&1
if [ $? == 0 ]; then
  echo "OK"
else
  echo "Install python-wnck"
  sudo apt -y install libwnck22
  wget -c http://archive.ubuntu.com/ubuntu/pool/universe/g/gnome-python-desktop/python-wnck_2.32.0+dfsg-4_amd64.deb
  sudo dpkg -i python-wnck_2.32.0+dfsg-4_amd64.deb
  sudo apt --fix-broken -y install
fi
sudo dpkg -l python-gnomekeyring >/dev/null 2>&1
if [ $? == 0 ]; then
  echo "OK"
else
  echo "Install python-gnomekeyring"
  wget -c http://archive.ubuntu.com/ubuntu/pool/universe/g/gnome-python-desktop/python-gnomekeyring_2.32.0+dfsg-4_amd64.deb
  sudo dpkg -i python-gnomekeyring_2.32.0+dfsg-4_amd64.deb
  sudo apt --fix-broken -y install
fi
sudo add-apt-repository -y ppa:screenlets/ppa
sudo sed -i 's/bionic/xenial/g' /etc/apt/sources.list.d/screenlets-ubuntu-ppa-bionic.list
sudo apt update && sudo apt -y install screenlets screenlets-pack-all

But all I get is this:

tobi@tobi-System-Product-Name:~$ #!/bin/bash
tobi@tobi-System-Product-Name:~$ sudo dpkg -l python-wnck >/dev/null 2>&1
tobi@tobi-System-Product-Name:~$ if [ $? == 0 ]; then

>   sudo dpkg -i python-wnck_2.32.0+dfsg-4_amd64.deb
>   sudo apt --fix-broken -y install
> fi
OK
tobi@tobi-System-Product-Name:~$ sudo dpkg -l python-gnomekeyring >/dev/null 2>&1
tobi@tobi-System-Product-Name:~$ if [ $? == 0 ]; then

OK

I think sudo apt-get update doesn't work for me, but I don't know how I can fix this.

Then please add output of apt-cache policy python3-software-properties to the question.
Tobi696 over 5 years

I have added it.
N0rbert over 5 years

Install normal version with sudo apt-get install --reinstall python3-software-properties=0.96.20.7.

E: The package python3-software-properties needs to be reinstalled, but I can't find an archive for it. (same error again)

Try to download and install it manually: wget http://mirrors.kernel.org/ubuntu/pool/main/s/software-proper‌ties/python3-softwar‌e-properties_0.96.20‌.7_all.deb and sudo dpkg -i --force-all ./python3-software-properties_0.96.20.7_all.deb followed by sudo apt-get install -f.

At the 2nd command I got this errror: dpkg: error processing package python3-software-properties (--install): installed python3-software-properties package post-installation script subprocess returned error exit status 127 Errors were encountered while processing: python3-software-properties

Try sudo dpkg --configure -a and sudo apt-get install -f, sudo apt-get dist-upgrade.

when doing the first, I got several errors which look like this: dpkg: error processing package apturl-common (--configure): dependency problems - leaving unconfigured

at the second and third: E: The package apturl-common needs to be reinstalled, but I can't find an archive for it.

It seems that you have serious breakage of your system. It is fixable, but you need to do many things by hand.

I actually install ubuntu just some weeks ago...

the problem is that I can't install about 60% of all linux applications because of this error
