I ran # aptitude install libreoffice-grammarcheck-en-gb and aptitude just carried on without asking as is correct when there is only one package; but it proceeded to uninstall my entire desktop environment, hundreds of packages. I couldn't believe it and used the bash history to confirm that that was ALL I had typed. Moreover, it wouldn't respond to control-C.
Whatever happened????? <groan. Sinks head in hands> And it isn't even my computer. Lisi
