Issue with vjul directory

[vnikoofard]

Hi,

I'm trying to update my Julia 1.7.3 installation using the following command
sudo ./jill.sh -u julia-1.7.3 But I get the following error
cp: cannot stat '/root/.julia/environments/vjul': No such file or directory
I also had installed the version 1.7.3 using jill.

Any help is appreciated.

Hi @vnikoofard, can you try -u 1.7 instead.

PS. Let me know if that works so I can update the documentation with something clearer.

Now it gives the following error

cp: cannot stat '/root/.julia/environments/v1.7': No such file or directory

But it's strange! I have this directory in my Home
/home/vahid/.julia/environments/v1.7

I think this is a corner case that we missed before. We use ~ for the -u option, so with sudo is default to /root/.
I think a workaround is

• run without sudo to copy the environment
• then run again with sudo to actually install in the correct place.

I'm confused, as you said ~/.julia/environments/v1.7 is pointing to /home/vahid/.julia/environments/v1.7 in command line.

I think I got it now. Try sudo -E ./jill.sh -u 1.7.

The explanation is from https://unix.stackexchange.com/questions/684395/tilde-expansion-vs-variables-in-bash.

It looks like sudo does not preserve your $HOME information, so it uses the roots $HOME, which is /root.
If you run with -E, it will use your $HOME, which is /home/vahid.

To test this, create a tmp.sh file with the contents echo ~, and run

bash tmp.sh
sudo bash tmp.sh
sudo -E bash tmp.sh

In my case it returned

/home/abel
/root
/home/abel

Excellent solution! Thanks Abel! Now the upgrading works fine.
Muito obrigado!

Ah, great news. I will try to improve the documentation for this case. Thanks for reporting this.
Also, could you leave your opinion on

Ah, just one more comment. After upgrading to 1.8 and copying the environments using jill, to update the package using Pkg it throws an error
ERROR: SystemError: opening file "/home/vahid/.julia/environments/v1.8/Manifest.toml": Permission denied
The workaround is run the Julia using sudo.

[abelsiqueira]

Thanks for the report.

To fix this you can change the ownership of the files in your environments like this:

sudo chown -R vahid:users ~/.julia/environments/v1.8

Check with ls -l in that folder.
