Termux app has no signature

Two days ago kcubeterm posted on this post saying that

have released a broken version of termux apps and realised too late. Now users are Reporting on our forums. We have released fixed versions but it takes while.
Is there any way to remove termux v0.105

Then Relan said

We can remove 0.105, but this change will take effect on the next index update. At the same time 0.106 will be published (build succeeded ), so all we can do is wait :slight_smile:

So @ReniSalcedo79 its not your problem and the solution is downgrade it to an older version and patiently wait for the next relese.
