Install a previous version of an App

[alfish2000]

Hi!

Had this problem right now and trying to get some insights.

I had jellyfin installed in v10.11.0 (https://github.com/ScoopInstaller/Extras/blob/master/bucket/jellyfin.json)
I have updated to v10.11.3
v10.11.3 seems to have a bug
So I wanted to try if a previous versions works.
Doing this
scoop install [email protected]
does not work:

WARN  Given version (10.11.2) does not match manifest (10.11.3)
WARN  Attempting to generate manifest for 'jellyfin' (10.11.2)

Which seems to be obvious because (https://github.com/ScoopInstaller/Extras/blob/master/bucket/jellyfin.json) only contains the URL path to the latest version.
scoop tries to guess the previous version somehow but fails because jellyfin only has the latest-stable version in the path in the manifest.

The remote server returned an error: (404) Not found.
URL https://repo.jellyfin.org/files/server/windows/latest-stable/amd64/jellyfin_10.11.2-amd64.zip is not valid
Could not install [email protected]

I think at this path the previous version would be: https://repo.jellyfin.org/files/server/windows/stable/v10.11.2/amd64/jellyfin_10.11.2-amd64.zip
Even using the previous manifest version acf12f4 would not help (if it would be possible somehow) because the URL would point to jellyfin_10.11.2-amd64.zip which is not in the "latest-stable" folder anymore.

So here some questions:

Installing a previous version only works, when the previous target version is still at the expected previous URL location.
So jellyfin might better use "https://repo.jellyfin.org/files/server/windows/stable/" in their manifest instead of "https://repo.jellyfin.org/files/server/windows/latest-stable/amd64/" were they seem to remove previous versions.

Wouldn't it be even better when the jellyfin.json manifest would properly contain previous versions so that scoop would not have to guess where the previous version could be?

In this scenario how could I install a previous version of jellyfin via scoop?
Changing the URL or so in my local jellyfin.json file?
Would that mess up something else?

I might have been lucky in this case because jelly v10.11.0 was still installed on my machine so I was able to rollback via

scoop reset [email protected]

But on a new machine I would not be able to install any previous version via scoop (without hacking anything?)

Exactly. This is an oversight in the manifest. Resolved in 1d867fa.

Currently, we can only guarantee that the manifest works for the latest version. For previous versions, if the URL in autoupdate field is not version-specific, or in cases like the one you mentioned where the URL cannot apply to older versions, Scoop cannot handle them correctly.

In this case, you can submit a PR to fix the issue and use it once it's merged.
Or you can manually edit a local copy of the manifest, but it will then use the local manifest and won't get updates anymore. e.g.,

scoop install "C:\Users\username\Desktop\jellyfin.json"
