[sane-devel] HP ScanJet Pro 2000 sudden failure

[Ellis Cohen]

Also:  assuming Fedora 32 is ok:  should I first 'sudo dnf remove sane-airscan' and then install from the URL?  I tried entering the 'remove' command (and then saying 'No' to "is this ok?"), and noticed that the remove of sane-airscan would also remove the following dependent packages

gscan2pdf   
hplip   
hplip-gui        
libsane-hpaio                            
sane-backends-daemon                               
sane-backends-devel                                         
sane-backends-drivers-cameras                     
sane-backends-drivers-scanners
