I had the similar issue while installing Tizen GBS package.
Only the below solution helped me:
- Manually download missed *.deb packages
- Copy packages to the /var/cache/apt/archives
- Run install command again
In this case apt tool checks the local availability of the package first.
If it is present under /var/cache/apt/archives path, then a download step (with hash-sum mismatch error) is skipped.
Example:
wget http://download.tizen.org/tools/latest-release/Ubuntu_16.04/amd64/librpm-tizen_4.11.0.1.tizen20140530-tizen20140723_amd64.deb
sudo cp librpm-tizen_4.11.0.1.tizen20140530-tizen20140723_amd64.deb /var/cache/apt/archives
