After I reinstalled Nethserver, then I installed it again, all the software on Nethserver, then I stopped in this package for a very long time until it didn’t work at all and just walked after 27 minutes of stoppin
Looks like the download of the package stopped. So it is likely that your internet connection was not stable, rather than the webtop package broken.
Can you roll back and try again?
The way is yes, but I have to wait 27 minutes for the new road and sometimes like to fail when I install Webtop, I download the same size software, just go fast the old Webtop.
Please, try from the command line:
yum install nethserver-webtop5
If a problem occurs, please paste here the output.
