I've create a backup of all the packages I've installed on one ubuntu server and try to restore it to a new ubuntu server.
I did the same as mentioned in the first answer of this question
Issue is after running the last two commands sudo dpkg --set-selections < ~/Package.list
& sudo apt-get dselect-upgrade -y
, I can't install new packages.
When trying to install pip3
, I have this error
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
python3-pip : Depends: python3-setuptools but it is not going to be installed
Recommends: build-essential but it is not going to be installed
Recommends: python3-dev (>= 3.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
One of the solution I found was to do a sudo dpkg --configure -a
But when running the command, this the trace I have
[my:/home/my]$ sudo dpkg --configure -a

I'm not sure what to do next.
