Ubuntu 18.04 href in RichText labels don't work
Using Ubuntu 1804 and Qt 5.11.1, hrefs to external websites do not seem to work anymore.
For example a link in a QMessageBox or a link in a QLabel with openExternalLinks=true.
They are throwing Error: no DISPLAY environment variable specified
Can anyone confirm this? maybe even with newer Qt versions
Seems like it only affects travis builds
From the looks of it you are trying to open web browser by activating that link, correct ? It's not likely that Travis provides a headless enabled web browser.
