Hello,

On Debian Trixie, I get the following error:

```
chris@SpaceballsTheDesktop:~/Downloads/makemkv-oss-1.18.2$ ./configure
configure: error: cannot find required auxiliary files: install-sh ltmain.sh config.guess config.sub
```

And I followed the steps for the required dependencies:

```
chris@SpaceballsTheDesktop:~/Downloads/makemkv-oss-1.18.2$ sudo apt-get install build-essential pkg-config libc6-dev libssl-dev libexpat1-dev libavcodec-dev libgl1-mesa-dev qtbase5-dev zlib1g-dev

You need to extract also those tar files. Downloading with Firefox, the files are double compressed. (tar.gz and inside of that is .tar)
Some kind of bug in Firefox.

Did you check the hashes of those files?
See here: viewtopic.php?p=187189#p187189

Also, as kop316 already told you, please make sure to properly extract them; execute this into the folder you downloaded the archives:
