Perian 1.2.2 on 10.6.7 - No Mountable File Systems

Postby mschwartz » Sat May 07, 2011 2:45 pm

Hi,

Trying to install 1.2.2. I had the prior version installed and was getting error msgs when attempting to upgrade. So I uninstalled Perian and am now trying to install using the DMG file from the site.

When I try to open the image, I get a warning dialog indicating "no mountable file systems".

Is the DMG file corrupted or is there some other problem? I have tried downloading the DMG image several times without resolution.

Thanks

Either you are using an OS below the required version for Perian or you have a corrupt download (either to your computer or a proxy sitting between you and the server).

If you re-read the subject line of my post, you will note that I am using OSX version 10.6.7, which is the latest version of OSX available (short of developer releases of Lion).

There is no proxy between me and your server.

Since I can download, open and install http://perian.cachefly.net/Perian_1.2.1.dmg without issue, this suggests that you have a problem with the 1.2.2 version file on the server or there is an incompatibility of some sort with OSX 10.6.7.

Perhaps you can provide a MD5 checksum for the file, which I can then compare with the download that I get, which would put to rest the issue of whether or not the file that I get is corrupted in some fashion.

Thanks.

HI there I have exactly the same issue as OP. I have tried updating via both the pref panel and also downloading directly from the Perian website. I have been trying to do this over the course of about a week and each time I have downloaded a fresh copy and get the same error message. I am on 10.6.7. I also am not on any kind of Proxy. Pref pane says it cannot extract the update and the downloaded .dmg says that there is no mountable file system.

ISPs often insert proxies that attempt to be transparent between their users an the rest of the network. They also tend to not tell their users of this fact.

$ shasum Perian_1.2.2.dmg
d112dbdda966882898a0d986e308ff6113a000d4 Perian_1.2.2.dmg

3651513 Apr 8 23:41 Perian_1.2.2.dmg

So a corrupted file is not the issue.

Then the fault lies entirely with your computer.

So why can I use the 1.2.1 version of the file from your server without issue and it would appear that at least one other person has the same issue now with the 1.2.2 file.

Have you downloaded the file on the server and attempted to install it on a system running 10.6.7?

Out of millions. That's hardly strong evidence.

Of course! I've done it several times over.

Try redownloading it with curl

curl -O path/to/file

Very Strange. I could not mount the dmg on either my MacPro or Macbook Pro, but I could open it on my wife's macbook. From there I copied the pref file over to the Macs and it installed Ok I think; although it did cause sysprefs to crash once

Hi, apologies for the delay in getting back here, but work was crazy the past few days.

I did use curl to download the file. I can open the DMG file, but get the following error dialog box, with a big red octagon and exclamation point:

Mac OS X can't repair the disk "Perian 1.2.2."

You can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can.


I frankly don't understand what is happening here if the SHA1 sum for the file is good, which suggests that the file is being downloaded with no corruption.

Hi,

I too am having this problem. I've downloaded the perian update many many times now. Always the same no mountable file system error. Most .dmg and .iso files seem to work but i have a few others besides perian that don't. If anyone finds the solution, please post it! thanks.

edit: by the way i'm running 10.6.8 now.
