I am trying to install the drivers for canon ts3150 on Ubuntu 18.04.3 LTS, Bionic. It's a wi fi printer and it sucessfully prints from my phone. I've tried
sudo add-apt-repository ppa:inameiname/stable
from Step by step instruction required to install Canon TS3150 Printer and got this 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://debian.neo4j.org/repo stable/ Release: The following signatures were invalid: EXPKEYSIG 26C95CF201182252 Neo Technology Admins <admins@neotechnology.com>
N: Skipping acquire of configured file 'universe/binary-i386/Packages' as repository 'http://miktex.org/download/ubuntu bionic InRelease' doesn't support architecture 'i386'
sudo add-apt-repository ppa:thierry-f/fork-michael-gruz also gives a very long error.
sudo apt install libxml2 libglade2-0 libpng12-0 libtiff5 gives the error:
Package libpng12-0 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libpng12-0' has no installation candidate
Also, downloading the drivers from https://asia.canon/en/support/0100910801 and trying sudo install.sh didn't work:
install.sh: command not found
