>From what I can tell, actually the escl buggy driver affects a wide range of Brother, Canon, Epson, HP, Ricoh, Xerox, apple-protocol scanners ......, although Mick reported his specific scanner, indications from sane devs and from debian bugs and other anecdotes suggest 'escl' 1.0.29 problems rather more widespread.
I really do think this is a special (and important) case for an LTS- distro, as MANY scanner manufacturers have taken up the airscan protocol and this provides a much easier scanning integration than lots of the individual protocols that came before. I do think this is doing a serious dis-service to Ubuntu LTS users, not to even modify the packages to produce a Warning message pointing at the correct fix, when escl module gets used, even if no extra package formally in focal. I do think it would be fair to get input from sane-devs etc... they too may be able to clarify how wide-spread issues are. I appreciate this may need to be looked at after Groovy released and after escl/airscan modules a bit further matured, etc, but I do strongly suspect not attending to this in some manner is going to perpetuate an increasing usability-headache, lots of duplicate bug reports, and so-on, throughout the life of focal LTS. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1897962 Title: Out of Memory Error with Brother DCP-J7720W Status in sane-backends package in Ubuntu: Fix Released Bug description: Installed XSane from the repository but when I scan the viewer screen is blank and if I try to save I get "Error during save: out of memory" I believe that escl driver in 20.04 sane-backends is a problem and it is related to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=962539 sane-backends 1.0.31 should be considered for focal-backports and that if possible, escl driver could be individually SRU (Stable release update) in focal-updates. ppa:sane-project/sane-git fixes the issue.
