PTY not working in Mintty
Fri Apr 10 12:05:46 GMT 2020
I have two machines in my posession: a desktop and a laptop. Both
machines have Windows 10 and the same up to date version of Cygwin
installed. The only difference is "age". The laptop is a new one, with
freshly installed OS and Cygwin, and the desktop is about one year old
and its hard drive is about 10 years old, Cygwin was installed a while
ago and periodically upgraded.
So far, on the desktop PTY does not work. Attempt to run docker (i am
using Docker Desktop for Windows) causes "Terminal is not a PTY" error,
i have to use winpty wrapper as suggested. On the laptop everything is
fine, docker works in MinTTY out of the box with no need for winpty.
Is there maybe some hidden setting, which got stuck somewhere in the
older system ? Why is PTY not working? Can anyone help me to diagnose that ?
