I have previously tried upgrade with devel repos. Did not work so well. Now I thought that I could ask some info about it. I took screenshots of what upgrades there is for my system. I now know that libmeipc0 will break the load applet and clockd will break the timesync. But that is all I know. I have now been trying to get cutetube working and have installed stuff according to given instructions in the cutetube thread. Now I am curious to know would there possibly be some updates which could change my situation. I also tried youtube-dl but could not update that either.

So I am interested to know:
1) Are there certain upgrades that everybody would benefit if they make them and which are in common use already with developer folks?

2) How to upgrade just certain application/package?

3) Or if there are more good upgrades than bad how to opt out the ones which are known to break things?

I updated maemosec-certman-ca by downloading it from devel pool and then with dpkg -i. It gave no dependency errors. Should I still install the rest stuff from the same pool directory or is there a way to check dependency problems in console? This openssl and certificate updates interest me the most cause I understand they are important and could help many.
