CI cannot set up environment correctly

[htwangtw]

Some tests are failing in #410 due to unable to install make and some basic packages such as curl tree.
Judging from #407, there might be some update on the Cirrus CI or Kubernetes in the past few weeks causing this issue. I cannot find the linux distro used to further debug this issue. It would be great to get some help from who knows this CI tool more.

Expected Behavior

CI should at least set up the environment correctly.

Actual Behavior

apt-get install -y make curl tree tar
Reading package lists...
Building dependency tree...
Reading state information...
Package make 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 'make' has no installation candidate
E: Unable to locate package curl
E: Unable to locate package tree
Exit status: 100
