Ok, this should put some people at ease. We haven't had much information on the #XZ debacle on the #LinuxMint side. We know that Mint is built on #Ubuntu and by extension #Debian. The obvious question: was Mint affected - the quick answer - No, that we know of, as of today. I did a fresh install of Virginia 21.3 and it comes with #liblzma5 version 5.2.5
You can check your own system to put your mind at ease - run: apt list liblzma5
