How to fix error when installing epson driver on linux?

Question

linux

Hello, Epson perfection v550 scanner. Sane does not support it, but the epson website seems to have a driver for this scanner. When installing, it writes this (sorry in advance for so many lines, but I'm a layman and don't understand anything):

I found out that as a usb device my scanner is visible, even the manufacturer is recognized, but refuses to scan, does not identify any scanners .
I will be very grateful for your help.

Answer 1

First things first, deal with the package repositories. crammed with a bunch of non-working garbage.
none of the lines from the specified log refers to the printer.
write in detail what and how you do to install the printer driver.

Answer 2

You need to clean up the connected repositories.
1. Add a key to the runscape repository:
2. Remove the repositories that were left, probably left after the update, or were abandoned:
ppa.launchpad.net/ubuntu-wine/ppa/ubuntu, ppa.launchpad.net/freyja-dev/unity-tweak-tool-daily, ppa.launchpad.net/upubuntu-com/gtk3themes/ubuntu. This is done by deleting the corresponding .list files in /etc/apt/sources.list.d or in "application sources" in settings.
