EdgeRouter ER-X Upgrade from 23.05 to 24.10 (Help!)

[xtcsero]

Hello,

I have an Edge Router X, and I want to upgrade OpenWrt from
23.05 to 24.10.

I followed these instructions:

GitHub - darkxst/erx-migration: Openwrt: Edgerouter X migration scripts for...

and I get the following error at the end: "Line 8: Syntax error: unexpected line break."

Can anyone help? What's wrong here?

How did the scripts end up on the router ?

[xtcsero]

I used WinScp Tool on Windows

[frollic]

And you c&p:ed it to a file on Windows from GitHub ?

[xtcsero]

Yes, I'm using a Windows PC.
I downloaded the files with Firefox and then copied them to the Temp directory
in OpenWrt using WinSCP. (I didn't edit the files.)

[frollic]

Try using wget directly from the router - https://raw.githubusercontent.com/darkxst/erx-migration/refs/heads/main/ubnt_erx_migrate.sh + https://raw.githubusercontent.com/darkxst/erx-migration/refs/heads/main/ubnt_erx_stage2.sh.

If it still fails, report the issue to the maintainer on GitHub.

It worked! Thank you for your help.
Apparently, the file was corrupted during the browser download.
