Solution 1

Try installing the software with

dpkg --install <Package_Name>

Like in your case just cd into the directory and then type the above command like

dpkg --install libpng12-0_1.2.50-2+deb8u3_amd64.deb

Solution 2

to install .deb packages use full path. say you have a .deb package in /home/yourname/Downloads/packagename.deb then use:

sudo apt-get install /home/yourname/Downloads/packagename.deb

Whenever I try to install some .deb packages which I downloaded before (e.g. Atom, BP-tools etc.) I receive this error in Ubuntu 17.10:
```
./bp-tools_17.12_amd64_Xenial_free.deb 
./bp-tools_17.12_amd64_Xenial_free.deb: line 1: syntax error near
unexpected token `newline' ./bp-tools_17.12_amd64_Xenial_free.deb:
line 1: `!<arch>'
```
can anyone help, please?

  are they really .deb files?; ie. if you file bp-tools*.deb do they report something like "Debian binary package (format 2.0)"

  You are trying to execute a .deb, .deb are not executable, you're expected to install them, for instance by using dpkg -i package.deb.
