I want to upgrade from svn 1.6 to 1.7 on my Ubuntu 10

I followed a few links over the internet to add some repositories such as https://askubuntu.com/questions/65468/where-can-i-find-a-subversion-1-7-binary and after trying some messy things, but I landed up getting stuck with this error whenever i type svn on the command line.

Svn: error while loading shared libraries: libserf-1.so.0 cannot open shared object file: No such file or directory

No matter how many times i remove and reinstall subversion and libserf1, nothing changes. The only thing i suspect is that i get this error message

WARNING: The following packages cannot be authenticated! libserf1 libsvn1 subversion

What should i do?

I had the same issue but did not want to reinstall subversion as noted above. I was able to create a sym link in /usr/lib to the existing .so file and that seems to have worked. I was able to do a checkout that gave me the error above before this:

Ubuntu 12.04 SVN 1.7, from http://ppa.launchpad.net/dominik-stadler

cd /usr/lib

Original Listing: -rw-r--r-- 1 root root 194514 Nov 1 14:53 libserf-1.a lrwxrwxrwx 1 root root 18 Nov 1 14:53 libserf-1.so -> libserf-1.so.1.3.0 lrwxrwxrwx 1 root root 18 Nov 1 14:53 libserf-1.so.1 -> libserf-1.so.1.3.0 -rw-r--r-- 1 root root 110056 Nov 1 14:53 libserf-1.so.1.3.0

Command: sudo ln -s libserf-1.so.1.3.0 libserf-1.so.0

Updated Listing: -rw-r--r-- 1 root root 194514 Nov 1 14:53 libserf-1.a lrwxrwxrwx 1 root root 18 Nov 1 14:53 libserf-1.so -> libserf-1.so.1.3.0 lrwxrwxrwx 1 root root 18 Dec 21 18:19 libserf-1.so.0 -> libserf-1.so.1.3.0 lrwxrwxrwx 1 root root 18 Nov 1 14:53 libserf-1.so.1 -> libserf-1.so.1.3.0 -rw-r--r-- 1 root root 110056 Nov 1 14:53 libserf-1.so.1.3.0

I realized that there is something to do with the repository dominik-stadler in the error message below.

WARNING: The following packages cannot be authenticated!
  libserf1 libsvn1 subversion
Authentication warning overridden.
Get:1 http://ppa.launchpad.net/dominik-stadler/subversion-1.7/ubuntu/ lucid/main libserf1 1.0.0-2ubuntu0~ppa3 [42.6kB]
Get:2 http://ppa.launchpad.net/svn/ppa/ubuntu/ lucid/main libsvn1 1.7.9-0svn1~lucid+svn1 [1,095kB]
Get:3 http://ppa.launchpad.net/svn/ppa/ubuntu/ lucid/main subversion 1.7.9-0svn1~lucid+svn1 [1,292kB]

So i went to first purged subversion & libserf1 i.e sudo apt-get purge subversion and sudo apt-get purge libserf1 , then went to /etc/apt/sources.list.d and removed the following files

dominik-stadler-subversion-1.7-lucid.list

dominik-stadler-subversion-1.7-lucid.list.save

and later a simple sudo apt-get install subversion installed everything perfectly.

I have no clue why/how this works, but thought i'd just document this here for someone else to benefit.
