Whenever I try to install phpmyadmin on my ubuntu server 18.04 I get the following errors
sudo apt install phpmyadmin php-mbstring php-gettext
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package phpmyadmin
E: Unable to locate package php-mbstring
E: Unable to locate package php-gettext
Most threads I ca find suggest reupdating and upgrading using apt, but doing so doesn't do anything, also I get that error on the fourth line
Err:5 http://ppa.launchpad.net/nijel/phpmyadmin/ubuntu bionic Release

E: The repository 'http://ppa.launchpad.net/nijel/phpmyadmin/ubuntu bionic Release' does not have a Release file.
Can someone help with this?
