Hi there,  
I’m using Ubuntu 20.04 and julia 1.5.2.  
I’m trying to use Plots. When typing

```julia
using Plots

```

the julia terminal raises no complaints. Then I tried

```julia
plot(1:3, 1:3)

```

and got the message

```julia
/home/inbar/.julia/packages/GR/BwGt2/src/../deps/gr/bin/gksqt: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory
connect: Connection refused
GKS: can't connect to GKS socket application

GKS: Open failed in routine OPEN_WS
GKS: GKS not in proper state. GKS must be either in the state WSOP or WSAC in routine ACTIVATE_WS
GKS: GKS not in proper state. GKS must be either in the state WSAC or SGOP in routine FILLAREA

```

and tens of other lines like the last one, with different routines. After that I tried running

```julia
gr()

```

and plot again, resulting in the first part of the message to disappear and the part with the routine failures to remain.  
What do I do wrong? Plots is a basic package, it doesn’t supposed to be that complicated to use it, is it?  
Thanks in advance.

I cannot replicate this. Try restarting (a) the REPL and doing

```julia
julia> using Pkg
julia> Pkg.update()
julia> using Plots
julia> plot(1:3, 1:3)

```

if that does not work restart your machine, and try it again (without doing anything else first). If you still get the same error or some other error, let us see it and also show us what `versioninfo()` prints.

</div>

using Pkg raised no remarks. Then:

```julia
julia> Pkg.update()
   Updating registry at `~/.julia/registries/General`
   Updating git-repo `https://github.com/JuliaRegistries/General.git`
┌ Warning: Some registries failed to update:

julia> using Plots

julia> plot(1:3, 1:3)
/home/inbar/.julia/packages/GR/BwGt2/src/../deps/gr/bin/gksqt: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory

```

and so on tens of the like lines. Also after restart.

```julia

I add that in ~/.julia/packages/GR have only two folders: BwGt2 and cRdXQ. I saw somewhere a comment about a folder named crXzk, maybe it has some relevance?

It is not ok that `update` does not work. That indicates a problem which can have many ramifications, none easy to know. You could try `Pkg.resolve()` … though its a long shot. You are better off removing some of the installation, and putting it back fresh but I am not the person to guide you for that.

OK, thanks.

People in [https://github.com/JuliaPlots/Plots.jl/issues/1649](https://github.com/JuliaPlots/Plots.jl/issues/1649) report that adding qt5 solves that issue
