Solved-Another Epson issue- req dependancies newer than in repo

[foghorn1966]

Trying to get my Epson GT-S50 scanner & image scan working on a Mint 20 LTS install.
The image scan package from Epson support site, when installing keeps hanging on a dependency version conflict.
The required dependencies are greater version numbers than those in the official Mint & Unbuntu repos.
The following is what I'm struggling with....
( I had this working on a Mint 19 install, might put that HDD back in)

Reading state information... Done
libpangomm-1.4-1v5 is already the newest version (2.40.1-4).
libusb-1.0-0 is already the newest version (2:1.0.21-2).
libc6 is already the newest version (2.27-3ubuntu1.4).
libstdc++6 is already the newest version (8.4.0-1ubuntu1~18.04).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
imagescan : Depends: libpangomm-1.4-1v5 (>= 2.42.0) but 2.40.1-4 is to be installed
Depends: libstdc++6 (>= 9) but 8.4.0-1ubuntu1~18.04 is to be installed
Depends: libusb-1.0-0 (>= 2:1.0.22) but 2:1.0.21-2 is to be installed
imagescan-plugin-ocr-engine : Depends: libc6 (>= 2.29) but 2.27-3ubuntu1.4 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

In search of a good suggestion or repo to add to get this working.
I have been trying & searching off & on for a couple of weeks now.

I think, You are try to install wrong version of packages. You can download packages for Linux Mint 19 series. https://support.epson.net/linux/en/imag ... linux_mint

Code: Select all

libpangomm-1.4-1v5 is already the newest version (2.40.1-4).
libusb-1.0-0 is already the newest version (2:1.0.21-2).
libc6 is already the newest version (2.27-3ubuntu1.4).
libstdc++6 is already the newest version (8.4.0-1ubuntu1~18.04).

These package versions are from Ubuntu 18.04 repos, so it looks like Mint 19.x installation, not 20.x.

Update: beat the issue to submission.....

Thanks kelebek333 & Monsta

I thought I was on a V20._ LTS & should have checked deeper on this

#Description: Linux Mint 19.3 Tricia
#Release: 19.3

GT-S50 needs iscan-gt-s80-bundle-2.30.4.x64 from the epson download site.

I had tried this version earlier but was hung on some "GCC" dependencies earlier that I found solutions for on an Ubuntu forum, that I forgot to make a note of for reference.

Fought with the supplied install script with the following error.

#E: The repository 'https://download.opensuse.org/repositor ... 9.10/amd64 bionic Release' does not have a Release file.
#N: Updating from such a repository can't be done securely, and is therefore disabled by default.
#N: See apt-secure(8) manpage for repository creation and user configuration details.
That specific repository directory is gone, no longer exists.

Installed Core package, then data package, followed by the two plugin packages.
Then struggled with "no connected scanner" faults in Image Scan, although system was kind of identifying it.

#$ lsusb
#Bus 003 Device 002: ID 04b8:0137 Seiko Epson Corp. ES-D200 [GT-S50]

#$ sudo sane-find-scanner
#found USB scanner (vendor=0x04b8 [Language Error], product=0x0137 [Language Error]) at libusb:003:002
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

#$ scanimage -L
#device `epkowa:interpreter:003:002' is a Epson (unknown model) flatbed scanner

This helped....
#sudo ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-gnu/sane

And permissions
#$ usermod -a -G scanner,plugdev (Me)

And this link...

creating an epson-libsane rules file

And then various adding & removing specific vendor & model in usb lines in the following created epson files in /etc/sane.d

epkowa.conf - had edited adding usb line with vendor & product, ended up commenting out & just having usb line.
epson.conf - as above
epson2.conf - as above
epsonds.conf still has the (usb 0x04b8 0x0137) line in it with just usb commented out.

Files in /etc/sane.d/dll.d as follows
imagescan - has epkowa line
iscan - has epkowa line

I'm not really sure what caused this to start to work other than the last edit was to the epkowa.conf file.

Just made notes to try to assist anyone else.
