I just upgraded to ubuntu 20.4. Trying to install locate resulted as follows :
sudo apt install mlocate
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package mlocate is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'mlocate' has no installation candidate
sudo apt update
and try again. – Archisman Panigrahi Sep 15 '21 at 07:25mlocate | 0.26-3ubuntu3 | focal | source, amd64, arm64, armhf, ppc64el, riscv64, s390x
