Dear all,

Since yesterday I’m having some issues for running of ccp4i2. At the begging I 
though it was a disk space memory problem but it wasn´t. I have re-install ccp4 
(indeed, I have tried with ccp4-8 and ccp4-9 installations) with the same 
result. I can run all other programs (ccp4, ccp4cloud…) but ccp4i2.

My machine is Ubuntu 22.04.4 and I have the error messages shown below when 
trying to execute ccp4i2.

Any help will be really appreciate

Best,
Marian
