If we try to migrate without "pull request" option than it works (but without merge requests being migrated).
The migration fails if both issues and pull requests are selected.
If we only choose issues than the issues are migrated.
If we only chose pull requests then the Gitlab merge requests are migrated.

I did have a look at #13884 however I did not see any errors relating duplicates (running gitea in dev mode)

I have found that the problem was that Gitea was searching for a nonexistent Issue:

[I] [SQL] UPDATE task SET repo_id = ?, status = ?, end_time = ?, errors = ? WHERE id=? [0 3 1615480073 issue does not exist [id: 0, repo_id: 202, index: 149] 102]

I created the issue ID 149 in Gitlab and then the migration succeeded.
So, it's not a duplicate entry issue

I investigated a bit further. The migration fails when there is a Gitlab merge request X but there is no Gitlab issue X.
By creating the Gitlab issue X the migration succeeds.

For example to create issues with a specific iid in Gitlab (say from #88 to #136):

for issue in $(seq 88 136) do echo "Creating issue $issue" curl --request POST \ --url https://gitlab.com/api/v4/projects/<Gitlab project ID>/issues \ --header 'content-type: application/json' \ --header 'private-token: <Gitlab API Token>' \ --data '{ "title": "Empty issue for Gitea migration", "iid": "'"$issue"'" }' done

The case of #13884 seems to happen when a merge request references an issue with the same id (not sure about this needs to be tested)
