problem installing packages via synaptic or mintinstall LMDE

[santiagorf]

Hi all,
I've installed LMDE 32bits a week ago, and since then I've been having problems installing applications with mintinstall. Every single time I run mintinstall, it freezes after either I enter the password, or I choose an application to be installed/removed.
If I use synaptic or mintupdate, I have the same luck, but after some trials/reboot I'm able to install/remove or update packages. I know LMDE is a rolling release and that this kind of problems might happen; however, as such applications are so critical I've started considering that there might be some problem in my computer.
Does anyone knows what is going on?
Thanks in advance.

ps: If I install/remove/upgrade using apt I have non of these problems.

try to do an upgrade to mintinstall and synaptic using apt-get and see if this solves your problem.

Same problem but with LMDE 64 bit too. Synaptic works fine thoug.

thanks lepadatu.lucian, I tried your suggestions, but I still have the same problem.
Mintupdate is just useless, as soon as its windows shows up, it gets blank, and I have to kill it.
Similar thing with mintinstall, after the window shows up, it goes blank 50% of the time. If it doesn't, when I try to install a new application, it freezes.
Fortunately, synaptic works (most of the time), so I can install applications form there or by using apt-get install.
The update, I do it through apt-get update/upgrade-dist.
