This belongs to bitbake-devel ML with [1.26] tag.

I believe it's this commit which fixes your issue:
commit 0e2f7e7663309daa46716e274fd85e9011120a7f

    fetch/hg: Disable checksums for archived downloads

Please test it in your environment and confirm, if it's not enough, then
there are 3 more mercurial fetcher commits in bitbake/master which are missing in 1.26:

3786472 bitbake: fetch2/hg.py: fix unpack error and mirror tarball
2df35a2 fetch/hg: Disable checksums for archived downloads
0276330 fetch2/hg.py: add clean function
f002b1c fetch/hg: support submodules
