synaptic transaction error message

[juanperucho]

A few months ago there was an Xorg update that trashed my install. After several days of trying to fix it, I decided to take a holiday from PCLinuxOS.
I missed it.
I tried to come back today.
I downloaded the latest minime and installed it. When I started installing apps, I got an error about apt not being able to ... transaction.
I wanted to give it one more opportunity and reinstall it once again.
Is there something I should know?

I got an error about apt not being able to ... transaction.

What was the precise message - forum members will need that to give an accurate response

[juanperucho]

The message was:

APT system reports E: transaction set check failed.

The question is simple:

If I want to reinstall, am I supposed to do something other* than install form the livecd and start installing new apps from syanptic?
(*: I mean: change sources.lst, aptupgrade or sth. like that)

Yes. You should be an advanced user who know what software they want and how to install and configure it as stated in the release notes. My suggestion is to install a few packages at a time or go with the Full version that doesn't require knowing this package needs to go in first before the other.

After installation one should always open Synaptic, click Reload --> Mark All Upgrades --> Apply then Apply again from the confirmation window to be fully upgraded and in sync with the repos. Only then should one try to install additional applications. Each time new application installations are desired, the same process needs to be first applied to resync the already installed packages to the current state of the repos.

Even the latest released ISO images  will be out of date almost immediately. The process of updating the repo packages never stops.

I've used PCLinuxOS for about 6 years now, so I've learned that lesson (probably the only one I've learned). Actually, this is the first time I haven't found any updates after installing.

Texstar:
I see your point, but I've always installed from minime. I thought synaptic took care of everything concerning dependencies.

I will give it another try with the piecemeal approach.

Thanks.

I reinstalled and the patient approach seems to be working.

I get the following error when trying to install okular (or evince)

Code: [Select]

APT system reports:
poppler-data is needed by libpoppler7-0.14.5-1pclos2010.i586
E: Transaction set check failed

[juanperucho]

I guess that's all.
I finished installing everything I wanted (two or three packages at a time) and I had no more problems.
(I can't read pdfs yet, since okular and evince are uninstallable, but I'll find a substitute for them).
