Hello,
I’m failing to use Plots on my work system which runs CentOS 7. When I try using Plots, I get this:
```julia

I have Julia 1.6.5.
Any help would be immensely appreciated!

Are you behind some sort of proxy or firewall? Can you try Julia 1.7 or the upcoming 1.8 release candidate (which I think have some changes to downloads)?

So are you suggesting that the problem is Julia being out-of-date? Our systems are administrated by another institution so I have to ask them to install Julia 1.7 for me.

Not exactly - Plots works just fine on 1.6.5, and if this is a download issue there’s likely a way around it (and you saying “systems are administered by another institution” increases the odds that it is a Downloads issue).
If it’s not easy for you to check with another Julia version you probably have to wait for someone who knows more about debugging artifact download issues like @mose

Did you try a clean environment?
```julia
mkdir test
cd test
julia --project="."
```
and then in Julia:
```julia
using Pkg
pkg"add Plots"
```

Thanks! Updating Julia solved the problem!
