I have 4 computers with PCLINUXOS, so far I have updated two, the update worked on one and the other failed.
I had downloaded the new version and installed it on the unit where it failed. The re-installation was so fast that I will do the new install on my two remaining unit.
Note that if you do a new installation, you will need to reinstall all other programs you has installed.
I just have one comment, who chose such an ugly splash screen? It resembles the hideous black tiled screen of a few years ago. Did we not learn from our previous mistakes?
