Looks like ghcup cannot find head.
Does ghcup install ghc head work?
Can you check the available versions by using ghcup list

[adithyaov]

Both the following fail:

sudo -- sh -c apt-get -y install ghc-head

ghcup install ghc head

One of them should succeed.

ghc-head is available in HVR PPA

sudo add-apt-repository ppa:hvr/ghc
sudo apt-get update

Does packcheck update the ppa?

ghc-head is available in HVR PPA

I used to run ghc-head CIs earlier. In fact we have an example in packcheck/travis config:

  #- env: BUILD=cabal-v2 GHCVER=head
  #  addons: {apt: {packages: [cabal-install-head,ghc-head], sources: [hvr-ghc]}}

[rnjtranjan]

ghcup list does not list "ghc head".

[harendra-kumar]

Can you try "base-4.16.0.0" instead of "head"? You will have to remove the GHCVER env var line in the env section above, other wise packcheck will fail because the ghc version is not actually base-4.16.0.0.

[harendra-kumar]

Change the ghc version to 9.2 instead of 9.2.0. ghcup does not install if specified as 9.2.0.

[harendra-kumar]

Let us install ghc via packcheck itself - composewell/packcheck#67 . It should be easy.

[harendra-kumar]

For now we can skip using haskell/actions/setup@v1 in the ghc head test and install it manually (using ghcup install ghc) in the script section before calling packcheck.

Added in #1429 . Closing this.
