如何让squashfs 和XZ 工作？

我正在努力快速掌握 Linux Mint，但我遇到了太多问题。

我做的第一件事是安装软件包 ( apt install snap)，然后意识到它被阻止了。所以我按照说明进行操作Snapcraft 网站，并删除/etc/apt/preferences.d/nosnap.pref。然后我重新安装了它（apt purge snap; apt install snap），重新启动并运行snap install hello-world。它下载了核心快照，当它尝试安装它时，它给了我以下错误消息：

error: cannot perform the following tasks:
- Mount snap "core" (10126) (cannot run unsquashfs: 
-----
Filesystem uses xz compression, this is unsupported by this version
Decompressors available:
    gzip
-----)

所以我去了squashfs LZMA 网站，下载 tarball 并解压。
当我运行时make，我收到以下错误：

cc -O2  -I. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -DCOMP_DEFAULT=\"gzip\" -Wall -DGZIP_SUPPORT -DXZ_SUPPORT -DXATTR_SUPPORT -DXATTR_DEFAULT   -c -o mksquashfs.o mksquashfs.c

我对 C 不太了解，但如果我能找到 .deb 包或其他东西，那就太好了。我尝试重新安装squashfs-tools，然后快照，然后重新启动，但这没有任何作用。

有人可以给我一些关于这个的指示吗？

PS 如果有更好的网站，请告诉我。
