Description:
This PPA contains VTE library from Ubuntu 20.04 LTS which is not affected by stupid bug https://pad.lv/1922276 . So user will be able to select all terminal output with full scroll-back in MATE Terminal and other VTE-based terminals as it is expected.

This PPA is useful for Ubuntu 22.04 LTS, Debian 11 (bullseye) and Debian 12 (bookworm).

As usual one can always remove this PPA and downgrade VTE packages by using `sudo apt-get install ppa-purge` and `sudo ppa-purge ppa:nrbrtx/vte`.
