In Extension manager there are two available extension updates that are shown when I check “Show all updates”.
In one of them (alternative searching), if I select it I get:
An error occurred: EndTag: '</' not found Line: 67 Column: 8
There’s no real update of this extension. This must be some error encountered in some past operation.
And the other (Zotero LO integration) shows:
An error occurred: Document is empty Line: 1 Column: 1
Again, this is most probably some failed installation in the past.
How do I get rid of these error messages?
