Error: (hls - 1.7.0.0 is already installed, The version 1.7.0.0 of the tool hls is not installed.)

I'm trying to install HLS 1.7.0.0 but I'm getting the following error on a NixOS system:

$ /home/brian/code/x86_64-linux-ghcup-0.1.17.7 --no-verbose install hls 1.7.0.0
[ Error ] (hls - 1.7.0.0 is already installed,
[ ...   ]  The version 1.7.0.0 of the tool hls is not installed.)
[ Error ] Also check the logs in /home/brian/.ghcup/logs

This seems like a big problem. It's already installed but not installed?

I've heard a report about this before, but the user didn't submit a proper bug report.

Please add additional information:

• ghcup debug-info
• run the command with the --verbose flag and attach the entire log
• attach the output of env
• attach the output of find ~/.ghcup
• is ~/.ghcup itself a symlink?
• did you change anything inside that directory manually?

I haven't done anything in that directory manually and it's a normal directory, not a symlink.

Was this the first time you installed HLS via ghcup? Did you do it via cli or TUI?

Originally VSCode tried installing it. For some reason ghcup just didn't realise the install failed.

I was able to force the install with the -f flag to try again and have gotten it to complete. Turns out the problems were:

1. I didn't have GNU Make available on the PATH
2. My TMPDIR didn't have enough space (ghcup warned me but I didn't see an extraction error so I ignored it)

Right. It seems this is a problem with cleanup on failure.

The directory /home/brian/.ghcup/hls/1.7.0.0 got created although installation failed. GHCup has very simplistic logic and uses certain internal directories to figure out if a tool is installed. For all other cases it deletes partial installation, but not for HLS, it appears.
