Same problem here. Can't install package.

Yep... happening for me too on 7.5.6!

Which packages are you unable to install?

Same for me. Using latest version of Umbraco 7.5.6 I tried to install Multi Url Picker and after waiting for the Uploading package progress bar to complete for a long time I realised it wasn't going to happen. Transferred installation to another server and same thing happened with this version.

Worked fine for me:

Was running from Visual Studio 2015 against SQL Server, and installed the package from a local file after downloading it. Umbraco 7.5.6.

You might want to check for errors in your Umbraco log and in your browser's developer console (I was using Chrome). Also be sure that Visual Studio isn't stuck with an exception dialog open.

By the way, you might consider Archetype as an alternative to Multi URL Picker: https://code101.net/links-in-umbraco-are-broken-but-alternatives-exist-1fe89aae2093

The package i tried to install, was a package i created in Umbraco v7.4.1, to export all the settings, doctypes etc to a new installation.

And the site was on a azure website.

Sounds like it might be a bug relating to something particular to that package. I'd recommend submitting a bug report here: http://issues.umbraco.org/issues

If the package has info you'd rather not have others see, I believe you can attach files to issues so that only Umbraco HQ can see them. Also, if you can get your error log, I'm sure that would be of use too.

It hung up for me using 7.5.6 using a SQL Server 2012 database trying to install a local package for uCommerce (https://our.umbraco.org/projects/website-utilities/ucommerce/). The package I was trying to install was uCommerceDemoStore-Razor_5.0.1.16343.zip. I too wound up just downgrading to 7.4.1 and then installing and upgrading afterwards to 7.5.6.

No, no errors appeared in the umbraco logs.

I have the same problem with a plugin, all I have is the manifest, css, js and single html file.

Uploads, and just sits on the screen afterwards... nothing in any of the logs.

Umbraco 7.5.6; with a package created from 7.5.6; looking at the package, I see nothing out of the ordinary.

I have the same issue, tested with 7.5.5, 7.5.6 and 7.5.7.

Version 7.5.4 works correctly for me

Thanks

I have seen this happen with Microsoft Edge. Installing via Chrome and Firefox worked fine.

I have reproduced this issue.

Very simple package created in 7.5.4 won't install to 7.5.7 in the exact same way. Just sits there saying "Uploading package".

No errors client or server side that I can see.

I'm experiencing this issue as well, with a barebones basic package, when locally installing.

Anyone yet know why this happens or what the solution is?

Try it with Chrome, it looks like a browser issue.

Targeted for a fix in 7.5.8 I believe... due out soon.

I do use Chrome. No luck :/

I don't know if this is of any use, but this is the error in my log:

Finally, today installed a new 7.5.8 and no problem with my custom package. Maybe it was an issue of the previous release.

Yep, it is fixed in 7.5.8 :-)

I have the same problem in v. 7.7. Site refreshes 5 to 6 times after uploading the zip file, then nothing happens ...

is working on a reply...
