Backports can help with that - those are built in stable, so will have the same compiler options as stable. Start by commenting out all sources pointing at unstable, add sources for jessie and jessie-backports and investigate which packages are installed at a higher version without backports. If some are missing and you think you need those versions, you can always do a local backport by rebuilding in jessie and ask on the backports list to see if someone else needs the same backport.

It's not about simply blocking installs - the package to be installed is being upgraded for a reason, so blocking the install just blocks the bug fix or blocks upgrades of other dependent packages, until the binary is rebuilt in stable. That's why the advice is to move this box to stable - ask for backports of any packages which need updates from testing. You have four years to decide whether to replace this hardware or continue running jessie without support. -- Neil Williams ============= http://www.linux.codehelp.co.uk/
