Teekin's questions

I run gVim from the command line and have for many, many years. But ever since upgrading to Ubuntu 18.04, I keep getting a long string of this warning a while after starting gVim:

** (gvim:5924): WARNING **: 15:10:26.274: invalid source position for vertical gradient

It's rather annoying because I keep using the terminal afterward and would like the content that was there before to stay there.

I haven't found anything useful searching for this warning online. I have no idea where it comes from or what it means.

Any help really appreciated.

I need a patch for mutt which is called "sidebar" and was a part of the mutt-patched package in Ubuntu 16.04. Now I've switched to Ubuntu 18.04 and it does not seem to exist in Ubuntu 18.04's repository.

The only instructions I can find online on how to install the "sidebar" patch is by applying the patch and compiling the package myself. I have the technical know-how to do that, but I don't like using hand-compiled software because then I'll have to manually check for updates instead of using the apt system.

Apt tells me that the package has been replaced by the mutt package:

[root@bonkwinkler ~]# apt-get install mutt-patched
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package mutt-patched is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  mutt:i386 mutt

E: Package 'mutt-patched' has no installation candidate
[root@bonkwinkler ~]# 

However, when running mutt, I'm shown a configuration error.

[helgihg@bonkwinkler ~]$ mutt
Error in /home/helgihg/.mutt/muttrc, line 47: sidebar_sort: unknown variable
Error in /home/helgihg/.mutt/muttrc, line 64: sidebar-scroll-up: no such function in map
Error in /home/helgihg/.mutt/muttrc, line 65: sidebar-scroll-down: no such function in map
Error in /home/helgihg/.mutt/muttrc, line 66: sidebar-scroll-up: no such function in map
Error in /home/helgihg/.mutt/muttrc, line 67: sidebar-scroll-down: no such function in map

So the patches in the old mutt-patched package do not seem to be included in the regular mutt package.

Does anyone have information about this, that might shed light on the problem?
