Can't Install System Dependencies on Zorin OS 18.1

[AztecTunes]

So I have been trying the past couple days to get this program to work, and I have manged to get every part of it working except the quick start to install the system dependencies. Every time I run it, the command instantly fails when it tries to add the i386 architecture. I have tried reinstalling with sudo dpkg, unistalling and reinstalling wine, and seeing if anyone else has ran into this issue one here or elsewhere, and so far no luck.

So I'm at a loss, and I don't trust my very minor knowledge of commands to help me work through the code on here. Any advice or help would be appreciated.

Here's the output I get when I run "Install System Dependencies" or "One Click Full Setup":
[00:44:31] • Installing System Dependencies [00:44:31] • ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ [00:44:31] • Installing dependencies for Zorin OS...

I've also had this issue for the past 2 weeks on Zorin 18.1 and have just found a fix with the help of Claude:

Cause
AffinityScripts/AffinityLinuxInstaller.py:7143-7144, in run_command. For sudo commands, it writes your password to the sudo process and then closes stdin itself:

proc.stdin.write(password_input)
proc.stdin.close()

Then it polls with proc.communicate(timeout=0.2). communicate() starts by flushing proc.stdin, and flushing a closed file raises ValueError: I/O operation on closed file. immediately. At that point sudo dpkg is still running, so the error handler kills it and reports failure.

Fix: add one line after the close so communicate() no longer touches the closed pipe:

proc.stdin.close()
proc.stdin = None

Workaround
run.py reuses its cached copy as long as the upstream commit (currently 09bc236) hasn't changed, so you can patch the cached file and run the installer again:

Run the installer (I'm using the newer Linux Affinity Manager here) but close the window without doing anything. so it creates a cached version of AffinityLinuxInstaller.py

curl -sSL https://github.com/jfacemyer/Linux-Affinity-Manager/raw/main/AffinityManager/run.py | python3

Then patch the version of AffinityLinuxInstaller.py in cache:

sed -i 's/^\( *\)proc\.stdin\.close()$/&\n\1proc.stdin = None/' ~/.cache/AffinityOnLinux/manager/main/*/AffinityScripts/AffinityLinuxInstaller.py

And run the installer again:

curl -sSL https://github.com/jfacemyer/Linux-Affinity-Manager/raw/main/AffinityManager/run.py | python3

If upstream pushes a new commit, run.py downloads a fresh copy and the patch is gone so the above would need doing again.

This worked perfectly thank you so much :D

Great, glad that worked and you're sorted now!

Yup this worked tremendously for my Linux Mint 22.3 Installation

I've submitted a PR to fix in source now.

Thanks for digging into this. It only bites on Python 3.12 and older (3.13 ignores that error), which is why it's showing up on Zorin and Mint. #233 fixes it here; until that's merged, the patch above gets around it.
