I fix this replacing juno for bionic on

/etc/apt/sources.list.d/appcenter.list
/etc/apt/sources.list.d/patches.list 
/etc/apt/sources.list.d/elementary.list 

to find this list of files you can use

sudo grep -R juno /etc/apt
  • I hope it works but I cannot confirm. I have meanwhile switched Linuxes in favor of Lubuntu 18.10-Lxqt. Until next time! – user170 Oct 18 '18 at 10:47
  • Can confirm the above works. Used find /etc/apt -type f -print0 | sudo xargs -0 sed -i 's/juno/bionic/g' to automate the process. – sudosensei Jan 14 at 13:53
  • Thank You (Can confirm the above works. Used find /etc/apt -type f -print0 | sudo xargs -0 sed -i 's/juno/bionic/g' to automate the process. – sudosensei Jan 14 at 13:53)... works for me fine – jaslavo Sep 19 at 16:04
