how do I downgrade google chrome?

Presumably after an update, google chrome has very serious problems with page rendering. I want to downgrade it. (Switching to vmlinuz.old and initrd.img.old did not help).

$ apt-cache policy google-chrome-stable
google-chrome-stable:
  Installed: 35.0.1916.153-1
  Candidate: 35.0.1916.153-1
  Version table:
 *** 35.0.1916.153-1 0
        500 http://dl.google.com/linux/chrome/deb/ stable/main i386 Packages
        100 /var/lib/dpkg/status

on a computer where google chrome works ok:

$ apt-cache policy google-chrome-stable
google-chrome-stable:
  Installed: 34.0.1847.132-1
  Candidate: 35.0.1916.153-1
  Version table:
     35.0.1916.153-1 0
        500 http://dl.google.com/linux/chrome/deb/ stable/main amd64 Packages
 *** 34.0.1847.132-1 0
        100 /var/lib/dpkg/status

(If I had the .deb on the 2nd computer, everything would be easier. But there's no .deb. And no old .deb's on the google site.)

So I try:

$ sudo aptitude install google-chrome-stable=34.0.1847.132-1
Unable to find a version "34.0.1847.132-1" for the package "google-chrome-stable"
Unable to find a version "34.0.1847.132-1" for the package "google-chrome-stable"
No packages will be installed, upgraded, or removed.

Need to get 0 B of archives. After unpacking 0 B will be used.

You see, it does not work. The Synaptic manager also shows no version that I could set.

So, how do I downgrade google-chrome-stable?

Probably someone knows an archive of old google-chrome .deb's?

An archive of old google chrome versions may be found at:

http://mirror.pcbeta.com/google/chrome/deb/pool/main/g/google-chrome-stable/

Unfortunately, google-chrome will tell you that the stuff in ~/.config/google-chrome is from a newer version. I renamed this directory to google-chrome_newer hoping to return to it when the problem with chrome is fixed.

EDIT There's no problem with that stuff from newer version, just press "ok". And I am afraid the chrome will never be fixed.

EDIT2

mirror.pcbeta.com does not work now. As usual, you may use https://archive.org/web/ .

The direct link to the page of interest is: https://web.archive.org/web/20160322044606/http://mirror.pcbeta.com/google/chrome/deb/pool/main/g/google-chrome-stable/

If you have problems connecting to web.archive.org, e.g. "DNS address could not be found", try to use the TOR Browser (probably with its "New TOR circuit for this site" feature, Ctrl+Shift+L).

On your 2nd computer

1. Your deb file is in:

   /var/cache/apt/archives
   

2. If not, install it again via:

   sudo apt-get install google-chrome-stable=34.0.1847.132-1
   

3. After that upgrade via:

   sudo apt-get dist-upgrade
   

On your 1st computer:

1. Transfer the file and install via:

   dpkg -i your.deb
   

2. And set the package google-chrome-stable on hold via

   sudo apt-mark hold google-chrome-stable
