I don't speak french, but google translate tells me that dpkg there is complaining that the colon (:) is missing after the field name in the dpkg database.
that to me sounds something like the user edited the file directly (and wrong) rather than anything else. Anyway, this is in an old untouched bug, which if that was the case it has been long fixed. I recommend you contact user support before filing a bug if you hit anything like this again. ** Changed in: vcdimager (Ubuntu) Status: New => Invalid ** Changed in: linuxmint Status: Triaged => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775466 Title: Cannot update LMDE.
