I have faced the same problem:
sudo dpkg -i ./sdkmanager_0.9.12-4180_amd64.deb
dpkg: error: cannot access archive ‘./sdkmanager_0.9.12-4180_amd64.deb’: No such file or directory
and when I try:
sudo apt install ./sdkmanager_0.9.13-4763_amd64.deb
Reading package lists… Done

Note, selecting ‘sdkmanager:amd64’ instead of ‘./sdkmanager_0.9.13-4763_amd64.deb’
Some packages could not be installed. This may mean that you have
