I recently removed python3 from my Ubuntu 18.04 system, and the next time I tried to logon I was greeted with a failed to start session error when entering my credentials. Unfortunately, Ctrl-Alt-F1 does not open a TTY for me. Trying CtrlAlt-F2 etc. also does nothing.

I am OK with re-installing Ubuntu, but unsure if this is necessary at this time.

    Please try Ctrl-Alt-F2 Ctrl-Alt-F3 Ctrl-Alt-F4 Ctrl-Alt-F5 and Ctrl-Alt-F6 then click on [edit] and report your findings. Please do not use Add Comment; instead, please use [edit]. – K7AAY Sep 27 '19 at 23:30
  • Maybe it's possible to install the packages from a live usb, chrooting your hard disk system. – schrodingerscatcuriosity Sep 27 '19 at 23:35

If friendlier options fail, you can try:

  1. Boot a live USB.

  2. Open a terminal and mount the partition where ubuntu lives:

    sudo mount /dev/sdX /mnt

  3. Chroot to your system:

    sudo chroot /mnt

  4. Now in the root environment it's possible you have to edit /etc/resolv.conf:

    nano /etc/resolv.conf

    add

    nameserver 8.8.8.8

    and save the file

  5. Run sudo apt update

  6. Run sudo apt install python3
  7. Close your live system and reboot.
