[MROSSFTEK]

when i go into the upgrade area, and i choose to install any beta versions, i get this error every time

PerformCoreUpgrade unTar error: unTar open src error: open : no such file or directory

Hi @MROSSFTEK, is your server in mainland China or any other region that has trouble to connect to GitHub?

[MROSSFTEK]

nope. i can pull the 'normal' upgrade versions, just not the preview versions.

[0xJacky]

Please use the script to upgrade,
https://nginxui.com/guide/install-script-linux.html

[MROSSFTEK]

im currently running Version: 2.0.0-rc.2 (384)

i just get that error when i got to "upgrade" and choose the pre-release channel.

[MROSSFTEK]

my full error screen is as follows when choosing pre release
Upgrading Nginx UI, please wait...

Initialing core upgrader

Downloading latest release

Performing core upgrade

Perform core upgrade error

PerformCoreUpgrade unTar error: unTar open src error: open : no such file or directory

im assuming i need to create a directory someplace?

Pre-release channel currently is behind the stable channel version, and I am not sure what happened, so please use the script to fix this problem.

If you previously used the installation script to install nginx-ui, you can check whether this path exists on your machine.

[MROSSFTEK]

yes that directory exists. like i said, everything works except being able to install pre releases. im find with installing the regular type updates, just thought you'd want to know the pre release version error. i have more than one server that has that same error. it used to work fine.

OK, thanks. However, this is essentially a downgrade operation, which can lead to database incompatibility issues at this stage. So please don't try to install the pre-release channel version for now. In the future, when v2.0.0 is officially released, we will fill in the pre-release with an updated version, which will address this issue.

In da1ed85, I modified the GetRelease function to compare stable and prerelease versions, returning the most recent release based on the publish date.
