Thanks for the tip! When I just tried that I got: # sudo apt install ghostscript=9.25~dfsg+1-0ubuntu1 libgs9=9.25~dfsg+1-0ubuntu1 libgs9-common=9.25~dfsg+1-0ubuntu1 Reading package lists... Done Building dependency tree Reading state information... Done E: Version '9.25~dfsg+1-0ubuntu1' for 'ghostscript' was not found E: Version '9.25~dfsg+1-0ubuntu1' for 'libgs9' was not found E: Version '9.25~dfsg+1-0ubuntu1' for 'libgs9-common' was not found #
Obviously I need to configure(?) something, but am at a bit of a loss as to what, as I don't really know much about the Debian/Ubuntu packaging system. (Any tips or pointers?) Fortunately, the "High Qualify Grayscale" CUPS workaround is Ok(-ish) for now.... cheers! -blf- On Fri, 22 Feb 2019 at 18:20, Jarl <1817...@bugs.launchpad.net> wrote: > I have downgraded to 9.25 using > sudo apt install ghostscript=9.25~dfsg+1-0ubuntu1 libgs9=9.25~dfsg+1-0ubuntu1 > libgs9-common=9.25~dfsg+1-0ubuntu1 > > That solved the problem. > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1817308 > > Title: > GhostScript Update causes Blue Background > > Status in ghostscript package in Ubuntu: > Incomplete > > Bug description: > I am running 64 bit Linux Mint 19.1, the Cinnamon desktop 4.0.9, with > kernel 4.15.0-45-generic. > > Two days ago an update to ghostscript dated 20 FEB 2019 appeared, and > was applied to two of my machines (One is an Intel and one is an AMD, > but both are kept fully updated) that share a networked HP OfficeJet > 6700 Printer. > > At some point following the update, I happened to print a document, > and ended up with a blue background on every page, even otherwise > blank second sides.
