Packer: iso_url path doesn't work for windows network paths

[ValTer25]

Hello.
up to this point, I was using version 1.3.3 and decided to upgrade to 1.5. but after updating the exe file, links to iso images stopped working
I use "iso_url": "\\server\share\en_windows.iso"
In the logs, I see that Packer tries to use the path (\server\share\en_windows.iso), and then converts it to (smb://server/share/en_windows.iso).
I also used the prefix file://, but it didn't help
hyperv-iso

Hi there! Thanks for opening this issue. We had an issue during that time where the packer_cache on windows was causing issues. Can you try clearing your packer_cache directory and then building again? If that doesn't resolve your issue, will you please share the simplest possible packer template that reproduces the issue, as well as the logs produced when you run the packer build after setting the environment variable PACKER_LOG=1?

I`m clearing packer_cache directory, but it didn't help

Looks like we introduced this bug here: https://github.com/hashicorp/packer/pull/7800 Sorry about that. I'll see if I can repro and fix it.

Meanwhile, do you think you can share logs from your 1.3.3 passing run so that I can compare?

[ValTer25]

Sorry, but we have a very short log rotation. Now I use symbolic links.

Here are the log from 1.3.5 passing run:

Ive tested and it works to get the file thrue smb but seems longer then usual to do download/cksum even after a second time test because of there is no cache anymore.
