<p>I installed TeXlive 2018 on Windows 8.1 a few months ago (when it 
just came out). I updated the installation a few times since that 
initial install, without any problems.</p>

<p>Today I wanted to get the latest files and I did the usual:</p>

<pre class="gmail-lang-tex gmail-prettyprint gmail-prettyprinted"><code><span class="gmail-pln">tlmgr update --self, </span></code></pre>

<p>followed by </p>

<pre class="gmail-lang-tex gmail-prettyprint gmail-prettyprinted"><code><span class="gmail-pln">tlmgr update --all</span></code></pre>

<p>This is what I get (seems similar to a problem reported on StackExchange two weeks ago for Windows 10). </p>

<p>[in fact it is the third run of <code>update --all</code>, before it failed for the <code>abnt</code> and <code>acmart</code> packages, hence the 
<code>skipping forcibly removed package abnt</code>
<code>skipping forcibly removed package acmart</code>
messages]</p>

<p>Any hint what the problem could be? </p>

<p>Thanks</p>

<p><strong>UPDATE:</strong></p>

<p>After getting the suggestion top try another mirror I trieds to re-install the package acmart (which was forcibly removed 
by tlmgr update in my second try) using a  Swiss repository. I still
 get a similar error message.</p>
